Abstract:
Reactions of HS-Arf (S-Arf = S-C6F5, S-C6F4-CF3) with AuI utilizing a new atom-economy method result in corresponding [Au(S-Arf)]n metal-organic coordination polymers, which were studied by DSC, SEM-EDX, TGA, IR, and PL. Treatment of these complexes with pyridine under mild conditions results in the transformation of the starting polymers into new [{Au(py)2}{Au(S-Arf)2}]n complexes of the polymeric structure, which were isolated and characterized by single-crystal X-ray diffraction (SCXRD). The linear [Au(py)2]+ cations combine with linear [Au(S-Arf)2]- anions via Au···Au interactions into infinite chains. Such interactions were studied by quantum-chemical calculations. Treatment of [Au(S-C6F4-CF3)]n with DMSO gives crystals of [Au4(S-C6F4-CF3)4]n·nDMSO that have a unique polymeric structure.

02:58Crystal Field Theory - Octahedral Complexes
To explain the observed behavior of transition metal complexes (such as colors), a model involving electrostatic interactions between the electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals.

02:46Crystal Field Theory - Tetrahedral and Square Planar Complexes
Crystal field theory (CFT) is applicable to molecules in geometries other than octahedral. In octahedral complexes, the lobes of the dx2−y2 and dz2 orbitals point directly at the ligands. For tetrahedral complexes, the d orbitals remain in place, but with only four ligands located between the axes. None of the orbitals points directly at the tetrahedral ligands. However, the dx2−y2 and dz2 orbitals (along the Cartesian axes) overlap with the ligands less than the dxy,...
