A one-dimensional copper(II) phenyl-ene-diphospho-nate: catena-poly[[(1,10-phenanthroline-?N,N')copper(II)]-?(3)-[m-phenyl-enediphospho-nato-?O:O':O'']].

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 ?-? 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.
