Layered iron(II) spin crossover complex constructed by NH?Br – hydrogen bonds with 2 K wide thermal hysteresis, [Fe IIH3LMe]Br¡¤CF3SO3 (H3LMe = tris[2-(((2-methylimidazol-4-yl)methylidene) amino)ethyl]amine)

A series of compounds [FeIIH3LMe] Br¡¤Y¡¤nMeOH (Y=PF6- (1), AsF6- (2), SbF6- (3), CF3SO3- (4); n = 0 or 1) were synthesized, where H3LMe is a hexadentate N6 tripodal ligand of the neutral form, tris[2-(((2-methylimidazol-4- yl)methylidene)amino)ethyl]amine, and their structures and magnetic properties were investigated. The compounds 1-3 with counter anions Y=PF6-, AsF6-, and SbF6- contain methanol as a crystal solvent, and show no SCO behaviors, while the corresponding Cl- compounds have no crystal solvent and show a variety of SCO behaviors. The compound [FeIIH3L Me]Br¡¤CF3SO3 (4) has no crystal solvent and has isomorphous structure to the Cl- compounds, and shows an abrupt spin transition between the HS (S = 2) and LS (S = 0) states with a hysteresis about 2 K and large frozen-in effect below 72 K. The T 1/2? and T1/2? values are 98 and 96 K, whose values are higher than those of corresponding Cl- compound about 15 K and the width of hysteresis is narrower than that of corresponding Cl – compound about 2 K. The crystal structures of 4 were determined at 296 and 93 K, where the crystal system and space group showed no change between these temperatures. The structures at both temperatures have a same 2D layered structure, which is composed of NH?Br- hydrogen bonds between the Br- ion and the imidazole NH groups of three neighboring cations [FeIIH3LMe]2+. This network structure is the same as that of corresponding Cl- compound. The 600 nm light irradiation at 5 K induced the LIESST effect.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 2926-30-9, help many people in the next few years.Recommanded Product: Sodium trifluoromethanesulfonate

Influence of the backbone of N5-pentadentate ligands on the catalytic performance of Ni(II) complexes for electrochemical water oxidation in neutral aqueous solutions

Two N5-chelated nickel complexes displayed decent catalytic activity and good stability for electrochemical water oxidation in phosphate buffer solutions at pH 7, with observed rate constants of 3.06 and 4.62 s-1, which are higher than those reported so far for molecular nickel catalysts in neutral solutions. The results revealed that the rigid backbone of N5-chelating ligands has a positive influence on the activity of the nickel catalysts.

Synthesis, characterization and anticancer activity of gold(III) complexes with (1R,2R)-(-)-1,2-diaminocyclohexane

Two gold(III) complexes, [(DACH)AuCl2]Cl (1) and [(DACH)2Au]Cl3 (2), derived from (1R,2R)-(-)-1,2-diaminocyclohexane and sodium tetrachloroaurate dihydrate, NaAuCl4¡¤2H2O, were synthesized and fully characterized using elemental analysis and different physical methods, such as FTIR, 1H NMR, 13C NMR, solid-state NMR and X-ray crystallography. The data confirm the coordination of the DACH ligand to the gold(III) metal centre through its nitrogen atoms. According to in vitro cytotoxic studies, complex 2 was more effective against the three human tumor cell lines evaluated (the ovarian cancer cell line A2780, its cisplatin-resistant clone A2780cis and the classical Hodgkin lymphoma cell line L-540). The fold-resistance of the A2780 and A2780cis cells to cisplatin was about twofold lower for both gold(III) complexes.

Rational design of homo and hetero hexanuclear coordination compounds: Syntheses and magnetic properties of hexacopper and diocopper tetranickel coordination compounds and the crystal structure of a hexacopper coordination compound (see abstract)

New homo- and heterometallic hexanuclear complexes of formula {[Cu(tmen)(H2O)]2[Cu(tmen)]2[Cu2L](H2O)}(ClO4)4 ¡¤ 2 H2O [Cu6- tmen] {[Cu(pmdien)]4[Cu2L]}(ClO4)4 ¡¤ 4 H2O [Cu6-pmdien] and {[Ni(cyclam)]4[Cu2L]}(ClO4)4 ¡¤ 4 H2O [Cu2Ni4-cyclam] [H8L = tetrakis(aminomethylene)methanetetrakis(oxamic acid), tmen = N,N,N’,N’- tetramethylethylenediamine, pmdien = N,N,N’N’,N”- pentamethyldiethylenetriamine, and cyclam = 1,4,8,11- tetraazacyclotetradecane] have been synthesized. The crystal structure of [Cu6-tmen] has been determined by single-crystal X-ray diffraction. The structure consists of cationic {[Cu(tmen)(H2O)]2[Cu(tmen)]2- [Cu2L](H2O)}4+ hexanuclear units. The hexanuclear cation is made up of two symmetry-related oxamato-bridged trinuclear units connected through the central carbon atom C(6) of the L8- ligand. Variable-temperature magnetic susceptibility measurements (1,8-300 K) have been performed for these series of complexes including the dinuclear precursors of formula Na4[Cu2L] ¡¤ 10.5 H2O [Cu2-Na], (NMe4)4[Cu2L] ¡¤ 4 H2O [Cu2-NMe4] and (PPh4)4[Cu2L] ¡¤ 6 H2O [Cu2-PPh4]. The magnetic data have been interpreted. Evidence of a weak intramolecular ferromagnetic interaction between the two Cu(II) ions in [Cu2L]4- has been observed. For the hexanuclear species, the interaction through the oxamato bridge was found to be equal to -6790, -2650, and -1643 yJ (-342, -133, and -82 cm-1) for [Cu6-tmen], [Cu6-pmdien], and [Cu2Ni4-cyclam], respectively. In these complexes, the weak intramolecular ferromagnetic coupling between the two Cu(II) ions within the dinuclear synthon was masked by intermolecular interactions or local anisotropy.

Phosphane tuning in heteroleptic [Cu(N^N)(P^P)]+ complexes for light-emitting electrochemical cells

The synthesis and characterization of five [Cu(P^P)(N^N)][PF6] complexes in which P^P = 2,7-bis(tert-butyl)-4,5-bis(diphenylphosphino)-9,9-dimethylxanthene (tBu2xantphos) or the chiral 4,5-bis(mesitylphenylphosphino)-9,9-dimethylxanthene (xantphosMes2) and N^N = 2,2?-bipyridine (bpy), 6-methyl-2,2?-bipyridine (6-Mebpy) or 6,6?-dimethyl-2,2?-bipyridine (6,6?-Me2bpy) are reported. Single crystal structures of four of the compounds confirm that the copper(i) centre is in a distorted tetrahedral environment. In [Cu(xantphosMes2)(6-Mebpy)][PF6], the 6-Mebpy unit is disordered over two equally populated orientations and this disorder parallels a combination of two dynamic processes which we propose for [Cu(xantphosMes2)(N^N)]+ cations in solution. Density functional theory (DFT) calculations reveal that the energy difference between the two conformers observed in the solid-state structure of [Cu(xantphosMes2)(6-Mebpy)][PF6] differ in energy by only 0.28 kcal mol?1. Upon excitation into the MLCT region (lambdaexc = 365 nm), the [Cu(P^P)(N^N)][PF6] compounds are yellow to orange emitters. Increasing the number of Me groups in the bpy unit shifts the emission to higher energies, and moves the Cu+/Cu2+ oxidation to higher potentials. Photoluminescence quantum yields (PLQYs) of the compounds are low in solution, but in the solid state PLQYs of up to 59% (for [Cu(tBu2xantphos)(6,6?-Me2bpy)]+) are observed. Increased excited-state lifetimes at low temperature are consistent with the complexes exhibiting thermally activated delayed fluorescence (TADF). This is supported by the small energy difference calculated between the lowest-energy singlet and triplet excited states (0.17-0.25 eV). The compounds were tested in simple bilayer light-emitting electrochemical cells (LECs). The optoelectronic performances of complexes containing xantphosMes2 were generally lower with respect to those with tBu2xantphos, which led to bright and efficient devices. The best performing LECs were obtained for the complex [Cu(tBu2xantphos)(6,6?-Me2bpy)][PF6] due to the increased steric hindrance at the N^N ligand, resulting in higher PLQY.
