A copper(II) chain compound with hydrogenphosphate bridges organized in a double-chain structure. Synthesis, structure and magnetic properties of [Cu(1,10-phenanthroline)(μ-HPO4)(H2O)2]n

A new Cu(II) chain compound, [Cu(1,10-phenanthroline)(μ-HPO4)(H2O)2]n1 has been synthesized hydrothermally and structurally characterized. The Cu(II) ion is tetragonally coordinated with a phen ligand and two aqua ligands in the equatorial plane and hydrogenphosphates as axial ligands, thereby forming a linear chain. The crystal lattice is formed from antiparallel chains, kept together by relatively strong phosphate-water H-bonds (intra- and intermolecular) and by interpenetrated stacking of the phen ligands with other chains. The magnetic susceptibilities are reported.
