The hydrothermal reactions of V2O5, a copper(II) source, 1,4-carboxy-phenylphosphonic acid, a bidentate organonitrogen ligand and HF provided a series of bimetallic organic-inorganic hybrid materials. [Cu(bpy)VO2(O2CC6H4PO3)] (1) is one-dimensional, while [Cu(bpa)VO(OH)(O2CC6H4PO3)] (2) and [Cu(phen)V2O4F(O2CC6H4PO3)] (3) are two-dimensional. In the absence of V2O5, a number of copper-organophosphonates were isolated. Compound 4 [Cu(phen)(H2O)(O2CC6H4PO3H)] is one-dimensional while [Cu3(bpy)2(O2CC6H4PO3)2] (5) is two-dimensional. Molecular structures were observed for [CuF(bpy)(H2O)(HO2CC6H4PO3H)] (6) and [Cu(bpa)(O2CC6H4PO3H)]·3H2O (7·3H2O).

Five chiral and achiral copper(II) carboxyphosphonates, namely, [Cu(4-cppH)(2,2′-bipy)(H2O)] (1: R-1 and S-1), [Cu9(4-cpp)6(2,2′-bipy)6] (2), [Cu3(4-cpp)2(2,2′-bipy)2] (3), [Cu3(4-cpp)2(1,10-phen)2]·4H2O (4), and [Cu(4-cppH)(1,10-phen)]·H2O (5), had been hydrothermally synthesized. Among them, 1 showed an unexpected 1D chiral helical chain from achiral carboxyphosphonate ligand by spontaneous resolution. In 2, the interconnection of {CuN2O3}, {CuO4}, and {CPO3} polyhedra formed a 1D chain. Such chains were further connected to a 2D layer through the carboxyphosphonates ligands. Compounds 3 and 4 were isostructural and exhibited a 2D layer, which was constructed from {CuO3N2}/{CuO4} polyhedra and the carboxyphosphonate ligands. In 5, the interconnection of neighboring {CuN2O3} polyhedra formed a dimer. These dimers were connected with the carboxyphosphonate ligands to form a chain. Interestingly, the homochiral copper(II) phosphonate (R-1 or S-1) could be obtained by utilizing the (+)-cinchonine or -cinchonidine as a chiral-inducing agent, confirmed by CD spectra. Besides, the surface photovoltage (SPV) properties of 1-5 revealed that they had positive SPV responses. The magnetic data indicated that 1, 2, 4, and 5 showed the presence of ferromagnetic couplings between magnetic centers.
