Synthesis and structure of a novel one-dimensional vanadate constructed from tetravanadate clusters linked via copper-organic complex moieties: [{Cu(phen)(H_2O)}_2V_4O_(12)]

摘要

A novel organic-inorganic hybrid copper vanadate [{Cu(phen)(H_2O)}_2V_4O_(12)] (1) (phen = 1,10-phenanthroline) was synthesized by the hydrothermal reaction of V_2O_5, CuCl_2 centre dot 2H_2O, phen and water. Complex 1 was characterized by elemental analyses, XPS spectrum, TG analysis, 1R spectrum and single-crystal X-ray diffraction. Compound 1 crystallizes in the triclinic system, space group Pi, a = l. 7715(16) A, b = 9.3157(19)A, c= 10.887(2) A, alpha = 89.35(3) deg, /3 = 69.63(3) deg, gamma = 76.41(3) deg , V=716.1(3)A~3, Z = 2, lambda(Mo-Kalpha) = 0.71073 A, and R(F) = 0.0648. The title compound contains a novel double-chain ribbon constructed from tetravanadate clusters linked through copper-organic complex fragments. To the best of our knowledge, compound 1 represents the first example of one-dimensional vanadium oxide complexes constructed from tetranuclear V_4O_(12)~(4-) clusters linked via metal-organic complex moieties.
