Abstract:
This paper describes hierarchical arrangement of three Ag+ and three Hg2+ ions using two disk-shaped hexa-monodentate template ligands in which three oxazolyl rings are arranged each on the two concentric circles. The hierarchical manner of ligand arrangement allows the selective binding of monocationic Ag+ and dicationic Hg2+ ions to the inner first and the outer second generation coordination sites, respectively. This hierarchically well-balanced metal assembly should arise primarily from a minimized electrostatic repulsion between positively charged six metal ions arranged within the heteronuclear complex.

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,...
