Five new metal diphosphonates, namely, [Cu(H2L1)(2,2'-bipy)] (1), [Cu(H2L1)(0.5)(H3L1)(2,2'-bipy)][(H2O)(3)] (2), [Cu-3(H2L1)(1.5)(H3L1)(3)(2,2'-bipy)(3)][H2O] (3), [Ni(4,4'-bipy)(H2O)(4)][H2L1] (4), [Cd(H2L1)(1,10-phen) (H2O)(2)][(H2O)(2)] (5), (H4L1 = (2,3,5,6-tetramethyl-1,4-phenylene) bis(methylene)) bis(phosphonic acid, 2,2'-bipy = 2,2'-bipyridine, 4,4'-bipy = 4,4'-bipyridine, 1,10-phen = 1,10-phenanthroline) have been synthesized from a methylated phosphonate ligand and characterized systematically. The single-crystal X-ray diffraction analyses reveal weak interactions play important roles in the speciation of metal phosphonates. The photophysical property of compound 5 was also investigated.
