Abstract:
In the hydrated complex tetra-kis-(μ-2-carb-oxy-6-nitro-benzoato-κ2 O:O')bis-(μ-3-nitro-benzene-1,2-di-carboxyl-ato-κ2 O:O')tetra-kis-[(1,10-phenanthroline-κN:N')copper(II)] hexahydrate, [Cu4(C8H4NO6)4(C8H3NO6)2(C12H8N2)4]·6H2O, the CuII centres exhibit distorted coordination geometries defined by nitro-gen atoms from chelating 1,10-phenanthroline ligands and oxygen atoms from 3-nitro-phthalate anions. The centrosymmetric mol-ecular assembly is consolidated by bridging carboxyl-ate groups, while the crystal packing is governed by hydrogen bonding and π-π stacking inter-actions between aromatic rings. The scattering contribution of one disordered water mol-ecule contribution was treated using the SQUEEZE procedure.

Crystal 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.

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,...
Metal-Ligand Bonds
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...
