Bis(tetra-phenyl-phospho-nium) tris-[N-(methyl-sulfon-yl)dithio-carbimato(2-)-κS,S']stannate(IV)
Abstract:
In the title complex, (C(24)H(20)P)(2)[Sn(C(2)H(3)NO(2)S(3))(3)], the Sn(IV) atom is coordinated by three N-(methyl-sulfon-yl)dithio-carbimate bidentate ligands through the anionic S atoms in a slightly distorted octa-hedral coordination geometry. There is one half-mol-ecule in the asymmetric unit; the complex is located on a crystallographic twofold rotation axis passing through the cation and bis-ecting one of the (non-symmetric) ligands, which appears thus disordered over two sites of equal occupancy. In the crystal structure, weak inter-molecular C-H⋯O and C-H⋯S inter-actions contribute to the packing stabilization.

Crystal 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,...
