Self-assembly of two novel 1D chains constructed from {P2Mo5} phosphomolybdate clusters linked through copper (II) complexes

Two novel 1D organic-inorganic hybrid materials based on phosphomolybdates clusters, [Cu(phen)(H2O)]3[(PO4)2Mo5O15]·5H2O (1), HNa[Cu(bpy)(H2O)]2[(PO4)2Mo5O15]·6H2O (2), (phen = 1,10-phenanthroline, bpy = 2,2′-bipyridine) have been solvothermally synthesized and characterized by the elemental analyses, IR, TG analysis and EPR. The single crystal X-ray diffraction reveals that the compound 1 is built from a propeller-shaped chain constructed from {(PO4)2Mo5O15}6− clusters linked through {Cu(phen)(H2O)}2+ components as blades. Also the compound 2 is based on {(PO4)2Mo5O15}6− polyoxoanion, further connected by {Cu(bpy)(H2O)}2+ subunits. The chains are integrated via hydrogen bonding and π-π stacking interaction to form a 3D framework.
