Multiple Bonds between Transition Metals and Main-Group Elements. 145. Coordination Chemistry of Dirhenium Heptaoxide: Covalent Adducts and “Ionic Perrhenyl-Perrhenates”
Dirhenium heptaoxide dissolves in donor solvents such as 1,2-dimethoxyethane, thf, and CH3CN to form adducts of the general formula O3ReOReO3.2L (L = monodentate ligand site). A strong reactivity enhancement of Re2O7 for alkylation, arylation, and similar reactions follows from this unsymmetric Lewis-base coordination. The terminal and bridging oxygens equilibrate in solution ((17)O NMR). These adducts exhibit unsymmetrical bent oxygen bridges in their solid state structures, e.g. O3ReOReO3.dme (X-ray diffraction study; crystal data: space group P21/c, a = 12.162(2) A, b = 10.830(1) A, c = 8.195(1) A, beta = 90.80(1)¡ã,Z = 4). With stronger, chelating N-donors L2 such as 2,2′-bipyridine, N,N’-dicyclohexyl-1,4-diazabuta-1,3-diene, and 2,2′-bis(pyrazolyl)propanethe Re2O7.2L complexes have rigid asymmetric bridges even in solution ((17)O NMR). Thermal decomposition liberates Re2O7 (EI-MS) and the respective ligand (EI-MS, TG-MS). With tridentate ligands L3 like tris(pyrazolyl)methane, 1,4,7-triazacyclononane (tacn), N,N’,N”-trimethyl-1,4,7-triazacyclononane (tacn*), 1,4,7-trithiacyclononane (ttcn), the Re-O-Re bridge breaks with formation of the ionic perrhenates [ReO3L3](1+)[ReO4](1-). An example is the ionic [ReO3(tacn*)](1+)[ReO4](1-), the structure ofwhich compound has been determined by X-ray diffraction (crystal data: space group P1-, a = 7.389(2) A, b = 9.143(2) A, c = 12.294(3) A, alpha = 83.68(2)¡ã, beta = 77.99(2)¡ã, gamma = 89.29(2)¡ã, Z = 2). Intermolecular hydrogen bridging plays a major role in the crystal packing of the ionic perrhenates.
The reactant in an enzyme-catalyzed reaction is called a substrate. Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction.I hope my blog about 3030-47-5 is helpful to your research. Electric Literature of 3030-47-5
