The synthesis, characterization, and catalytic activity of bis(2-pyridylmethyl)amine (BPMA) copper complexes incorporating olefinic pendent arms are reported. Four copper(I) and four copper(II) complexes were synthesized employing four different counterions [chloride (Cl-), perchlorate (ClO4-), trifluoromethanesulfonate (CF3SO3-), and tetraphenylborate (BPh4-)]. The counterions used ranged from coordinating (Cl-) to non-coordinating (BPh4-), producing different coordination modes in respective complexes. Solid state results obtained for the copper(I) complex incorporating the non-coordinating (BPh4-) counterion displayed an associative bond between the metal center and the C=C group in the olefinic arm of a neighboring complex. This interaction led to augmentation of the C=C bond due to back-bonding from the metal center. Five solid state structures were obtained for the copper(II) complexes with two also displaying intermolecular associative bonding between olefinic pendent arms and the metal center. X-ray crystallography studies showed that the olefinic arm motifs incorporated were hemilabile. Solution studies indicated that the copper complexes had some inherent reducing power and could be potential candidates for use as catalysts in atom transfer radical processes. However, only moderate conversions and yields were obtained in atom transfer radical addition (ATRA) reaction studies performed utilizing the copper complexes due to the presence of a competing reaction.

Molybdenum-catalyzed conversion of molecular dinitrogen into ammonia under ambient reaction conditions has been achieved by using a proton source generated in situ from the ruthenium-catalyzed oxidation of water in combination with visible light and a photosensitizer. The preset reaction system is considered as a new model for the nitrogen fixation by photosynthetic bacteria.

Two-dimensional cyanide-bridged M(III)Ni(II) bimetallic assemblies, [Ni(1,1-dmen)2]2[M(CN)6]tfs*3.5H2O (M=Fe (1), Co (2); 1,1-dmen=1,1-dimethylethylenediamine, tfs(-)=trifluoromethanesulfonate ion), have been prepared. Each compound forms a 2-D grid structure extended by the M-CN-Ni linkages. Compound 1 shows a ferromagnetic ordering below Tc of 8.9 K based on a ferromagnetic interaction between low-spin Fe(III) and high-spin Ni(II). MCD spectra for 1 show a strong Faraday ellipticity at ca. 470 nm associated with the LMCT band of the Fe-CN bond. Its intensity increases with lowering temperature due to ferromagnetic ordering over the lattice. Compound 2 is paramagnetic and shows no remarkable Faraday effect.

The anionic complex [Ir(2-phenylpyridine)2(benzene-1,2-dithiolate)]- ([IrSS]-) is a nucleophile and metalloligand that reacts with methyl iodide and AuPR3+ (R = Ph or Et) to form S-methylated complexes (thiother-thiolate and dithiother complexes) and S-aurated complexes, respectively. The reactions are completely diastereselective, producing only the enantiomers lambdaS and deltaR or lambdaSS and deltaRR. The diastereoselectivity is stereoelectronically controlled by the orientation of the highest occupied molecular orbital (HOMO) of [IrSS]- arising from filled dpi-ppi antibonding interactions, and the chirality of the iridium ion. Methylation or auration removes the high-energy lone pair of the thiolate S atom, leading to low-lying HOMOs composed mainly of the Ir d-orbital and the 2-phenylpyridine pi (ppypi) orbital. The methylated and aurated complexes can be oxidized by H2O2 or peracid to give sulfinate-thiother, disulfoxide, and sulfinate-sulfoxide complexes, and the oxygenation further stabilizes the HOMO. All the complexes are luminescent, and their electronic spectra are interpreted with the aid of time-dependent density functional theory calculations. The thiother-thiolate complex exhibits ligand(S)-to-ligand(pi of ppy)-charge-transfer/metal-to-ligand-charge-transfer absorption (LLCT/MLCT) and a relatively low-energy 3LLCT/MLCT emission, while the other complexes display 3pipi/MLCT emissions.

The monoesters of mono- (1a), di- (1b), tri- (1c) and tetra- (1d) ethylene glycol with 3,4,5-trisbenzoic acid (1), the polymethacrylates derived from them (2) and the complexes of both 1 and 2 with LiCF3SO3 and NaCF3SO3 self-assemble into cylindrical supra molecular architectures which exhibit a hexagonal columnar (Phih) mesophase.The generation of the Phih mesophase depends on the stabilization of this assembly by endo-recognition in the core of the cylinder (H-bonding and ionic interactions) and exo-recognition that occurs between the tapered groups and also between the cylinders (i.e., the hexagonal arrangement of the columns).The low molecular weight compounds 1 are able to complex more salt in the Phih mesophase and have larger increases in Phih-isotropic transition temperature (TPhih-i) per increase in salt concentration than the corresponding polymethacrylates 2 derived from them.Molecular modelling appears to indicate that positional and conformational restrictions imposed by both the tapered side groups and the polymer backbone are responsible for these results.Both the polymers and the low molar mass compounds have their TPhih-i shifted to lower temperatures and allow more LiCF3SO3 to be complexed with the increase in the number of oxyethylene segments present in the flexible spacer.A comparison of the difference in the effectiveness of the Li cation versus the Na cation in providing increased stabilization of the Phih mesophase does not show any significant differences between the two cations.

The dinuclear cation [(eta6-C6Me6)2Ru2 (mu2-H)3]+ (1) reacts in aqueous solution with hydrazine to give the dicationic complexes [(eta6-C6Me6) 2Ru2(mu2-H)2 (mu2-eta1,eta1-H2NNH2)]2+ (2) and [(eta6-C6Me6)2Ru2 (mu2-H)(mu2-eta1,eta1 -H2NNH2)(mu2-NH2)]2+ (3). The single-crystal X-ray structure analyses of 2 (tosylate salt) and 3 (triflate salt) reveal both complexes to contain an intact hydrazine ligand coordinated parallel (mu2-eta1,eta1) to the diruthenium backbone, comprising a Ru=Ru double bond (2.69 A) in 2 and a Ru-Ru single bond (2.85 A) in 3. A single crystal of the mixed sulfate-hexafluorophosphate salt of [(eta6-C6Me6)2Ru2 (mu2-H)(mu2-eta1,eta1 -H2NNH2)(mu2-N2H3)] 2+ (4), isolated from the mother liquor of 2, suggests this hydrazido complex to be an intermediate in the reaction from 2 to 3.

A comparative vibrational spectroscopic study of 2-methoxyethyl ether solutions containing dissolved LiCF3SO3 and NaCF3SO3 is reported. The strong, infrared active metal oxygen stretching mode was observed as a broad band at 400 cm-1 in the LiCF3SO3 solution and at 180cm-1 in the NaCF3SO3 solution. Several low-frequency modes originating in intramolecular CF3SO-3 motions are reported and assigned. The relative concentrations of the various ionic species present are described as a function of salt concentration in both systems. Finally, changes in the local conformation of the 2-methoxyethyl ether backbone due to interactions of the ether oxygens with the cations are discussed.

We previously reported that iridium complex 1a enables the first homogeneous catalytic dehydrogenation of neat formic acid and enjoys unusual stability through millions of turnovers. Binuclear iridium hydride species 5a, which features a provocative C2-symmetric geometry, was isolated from the reaction as a catalyst resting state. By synthesizing and carefully examining the catalytic initiation of a series of analogues to 1a, we establish here a strong correlation between the formation of C2-twisted iridium dimers analogous to 5a and the reactivity of formic acid dehydrogenation: An efficient C2 twist appears unique to 1a and essential to catalytic reactivity.
