Structure of palladium bis(hexafluoroacetylacetonate) and the systematics of its acid-base chemistry

“…5 The melting point and heat of fusion, determined by differential scanning calorimetry, are 99.6 °C and 5.30 kcal/mol. X-ray powder pattern [d, Á (7//0)]: 8.91 (100), 2.77 (40), 3.05 (60), 6.06 (33). Electronic spectrum (cyclohexane): Xma, at 340 (sh) and 356 nm (log e = 3.86).…”

Static and dynamic Jahn-Teller distortions in CuN6 complexes. Crystal structures and EPR spectra of complexes between copper(II) and rigid, tridentate cis,cis-1,3,5-triaminocyclohexane (tach: Cu(tach)2(ClO4)2, Cu(tach)2(NO3)2. Crystal structure of Ni(tach)2(NO3)2

“…It has become increasingly clear during the last few years2,3 that the strong topological effect of the d9 electronic configuration on the potential energy surface is reflected in many features of the coordination chemistry of Cu(II) in general,1,3 even though some complications enter an adequate theoretical description of complexes with nonequivalent ligand atoms in the first coordination sphere. 38 The expectation that the local cluster potential energy surface is relatively inert against modifications by intermolecular forces and also the validity of eq 4 and 5 can be checked experimentally with the help of structural and spectroscopic data for different solids containing the same Cu(lig)/4" complex ion. 1.4.…”

Kinetic study of the metalation reaction of 5,10,15,20-tetrakis(pentafluorophenyl)porphyrin with water and methanol adducts of bis(1,1,1,5,5,5-hexafluoropentane-2,4-dionato)zinc(II) in supercritical carbon dioxide: specific cosolvent effect on the metalation

“…Such dependence is evidence for significant formation amounts of the outer-sphere association complex prior to the formation of metallporphyrin. In the present system, the reaction bimolecularly proceeds between H 2 tpfpp and [Zn(hfac) 2 L 2 ], because the equilibrium constant for the outer-sphere association was evaluated to be less than 10 2 mol −1 dm 3 , which is much smaller than that (about 10 3 2 ] strongly indicate that the two adduct molecules in [Zn(hfac) 2 L 2 ] are in the cis position (as seen in many single crystals of the Zn(II)-hfac complexes [33][34][35][36][37]), where the outer-sphere association is unfavourable, because cis-[Zn(hfac) 2 L 2 ] is not planar.…”
