摘要

Reactions in the CuSO4-phen-KVO3-H2O-(KOH) systems under non-hydrothermal conditions yielded seven new compounds: [Cu-2(H2O)(2)(OH)(2)(phen)(2)][Cu-2(OH)(2)(phen)(2)(V4O12)]center dot 6H(2)O (3), [Cu-2(phen)(4)(V4O12)]center dot 4H(2)O (4), [Cu-2(phen)(4)(V4O12)]center dot 6H(2)O (5), [Cu-2(phen)(4)(VO3)(4)]center dot 10H(2)O (6), [Cu(phen)(3)](2)V4O12 center dot phen center dot 22H(2)O (7), [Cu(phen)(VO3)(2)] (9) and [Cu-2(phen)(4)(V4O12)]center dot 4H(2)O (12). The prepared compounds were characterized by elemental analyses and IR spectra. The characteristic bands in the IR spectra corresponding to the V-O stretching modes enabled the different oxovanadate groups present in the structures to be unequivocally distinguished. Compounds 3, 4, 5, 6, 7 and 12 were characterized by X-ray single crystal diffraction. The structure of compound 3 consists of isolated dinuclear [(phen)(H2O)Cu(mu-OH)(2)Cu(phen)(H2O)](2+) ions and [(phen)Cu(OH)(2)Cu(phen)](2+) moieties attached to V4O124- rings. The structures of compounds 4, 5 and 12 contain [Cu-2(phen)(4)(V4O12)] clusters with different bonding modes of Cu(phen)(2)(2+) and V4O124- moieties. The structure of compound 7 is constructed by isolated [Cu(phen)(3)](2+) and V4O124- ions as well as molecules of uncoordinated 1,10phenanthroline and water of crystallization, while a polymeric structure containing (VO3)(n)(n-) chains, to which Cu(phen)(2)(2+) fragments are attached through Cu-O bonds, was found for 6.
