Abstract:
A dinuclear silver(I) com-plex of 6-phenyl-2,2':6',2''-terpyridine, bis-(μ-6-phenyl-2,2':6',2''-terpyridine)-bis-[(tri-fluoro-methane-sulfonato)-silver(I)], [Ag2(C21H15N3)(CF3SO3)2], was obtained by crystallization with silver tri-fluoro-methane-sulfonate and characterized by single-crystal X-ray diffraction. Two symmetry-related terpyridine ligands bridge two AgI ions. The AgI ion has a highly distorted four-coordinate N3O environment com-prising three pyridyl N atoms and one tri-fluoro-methane-sulfonate O atom. The intra-molecular Ag⋯Ag separation of 2.8501 (8) Å is consistent with an argentophilic inter-action. An intra-molecular phen-yl-pyridyl π-π contact is also present. The structure demonstrates that a single phenyl substituent at the 6-position is com-patible with ligand bridging and the formation of a short Ag⋯Ag contact.

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,...
