Abstract:
The title compound, [Cu(1,3-HO(3)PC(6)H(4)PO(3)H)(C(12)H(8)N(2))](n), is a coordination polymer of the metal-diphospho-nate family. The chain structure is constructed from '4+1' square-py-rami-dally coordinated copper(II) atoms bonded to chelating phenanthroline (phen) ligands and linked through 1,3-phenyldihydrogendiphospho-nate ligands. The basal plane of the Cu(II) site is defined by the phen nitro-gen donors and phospho-nate oxygen atoms from two diphospho-nate ligands, while the apical position is occupied by an oxygen donor from a third diphospho-nate ligand. The chains propagate along the a-axis direction. Inversion-related phen groups engage in π-π stacking with a mean distance of 3.376 (2) Å between the ring planes. O-H⋯O hydrogen-bonding inter-actions between the protonated {P-OH} groups of one chain and the {P=O} groups of adjacent chains stabilize the crystal packing.

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...

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.
