Abstract:
In the title polymer, {[Cu(C(8)H(12)N(2)O(6)P(2))]·2H(2)O}(n), the geometry of the five-coordinate Cu(II) ion can best be described as slightly distorted square-pyramidal formed by one N and two O atoms of an N(CH(2)PO(3)H)(2) group and one N atom from a pyridine ring. The elongated apex of the pyramid is occupied by one O atom from a third diphospho-nate ligand. The inter-connection of Cu(2+) ions by the diphospho-nate ligands results in the formation of a double-chain array along the b axis, in which the two sub-chains are inter-locked by pairs of PO(3) groups. The outside of each sub-chain is decorated by other PO(3) groups. These double chains are further assembled into a three-dimensional supra-molecular architecture via a large number of O-H⋯O hydrogen bonds between the phospho-nate groups and lattice water mol-ecules.

Colors and Magnetism
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human eye.
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...
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,...
