| Description | Reactions in the CuSO4–phen–KVO3–H2O–(KOH) systems under non-hydrothermal conditions yielded seven new compounds: [Cu2(H2O)2(OH)2(phen)2][Cu2(OH)2(phen)2(V4O12)].6H2O (3), [Cu2(phen)4(V4O12)].4H2O (4), [Cu2(phen)4(V4O12)].6H2O (5), [Cu2(phen)4(VO3)4].10H2O (6), [Cu(phen)3]2V4O12.phen.22H2O (7), [Cu(phen)(VO3)2] (9) and [Cu2(phen)4(V4O12)].4H2O (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)2Cu(phen)(H2O)]2+ ions and [(phen)Cu(OH)2Cu(phen)]2+ moieties attached to Click to view the MathML source rings. The structures of compounds 4, 5 and 12 contain [Cu2(phen)4(V4O12)] clusters with different bonding modes of Click to view the MathML source and Click to view the MathML source moieties. The structure of compound 7 is constructed by isolated [Cu(phen)3]2+ and Click to view the MathML source ions as well as molecules of uncoordinated 1,10-phenanthroline and water of crystallization, while a polymeric structure containing Click to view the MathML source chains, to which Click to view the MathML source fragments are attached through Cu–O bonds, was found for 6. |
