Solid-State Coordination Chemistry: Structural Influences of Copper−Phenanthroline Subunits on Oxovanadium Organophosphonate Phases. Hydrothermal Synthesis and Structural Characterization of the Two-Dimensional Materials [Cu(phen)(VO)(O3PCH2PO3)(H2O)], [{Cu(phen)}2(V2O5)(O3PCH2CH2PO3)], and [{Cu(phen)}2(V3O5)(O3PCH2CH2CH2PO3)2(H2O)] and of the Three-Dimensional Phase [{Cu(phen)}2(V3O5)(O3PCH2PO3)2(H2O)]

The hydrothermal reactions of CuCl2*2H2O, Na3VO4, 1,10-phenanthroline, and the appropriate organodiphosphonate ligand yield [Cu(phen)(VO)(O3PCH2PO3)(H2O)] (1), [[Cu(phen)]2(V2O5)(O3PCH2CH2PO3)] (2), [[Cu(phen)]2(V3O5)(O3PCH2CH2CH2PO3)2 (H2O)] (3), and [[Cu(phen)]2(V3O5)(O3PCH2PO3)2(H2O)] (4). Compounds 1-3 exhibit two-dimensional structures. The structures exhibit distinct vanadium building blocks: square pyramidal, mononuclear V(IV) sites in …
