Abstract:
In the title centrosymmetric binuclear complex, [Y(2)(C(10)H(6)NO(2))(6)(H(2)O)(4)]·2H(2)O, each Y(III) atom is nine-coordin-ated by nine O atoms from five ligands and two water mol-ecules in a slightly distorted monocapped square-anti-prismatic coordination environment. The Y(III) atoms are separated by a distance of 4.0363 (9) Å. The ligands coordinate in three different modes: chelating, bridging and a mixed chelating bridging mode. In the crystal structure, the binuclear complexes are linked by O-H⋯O and O-H⋯N hydrogen bonds, forming a three-dimensional network.

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,...
