摘要：

An unprecedented 1:1:1 comp lex [VO(bipy)(cit[H] H)]center dot 1.5H(2)O was obtained from the reaction of vanadium( III) chloride, 2,2 '-bipyridine (bipy), and citric acid (cit([H])H(3)) in methyl alcohol/water. The citrate anion (cit([H])H)(2-) chelates the metal centre as a tridentate ligand via the unusually protonated alpha-alcoholic group, and two oxygen atoms from the alpha- and one beta-carboxylate groups, the other beta-carboxylic acid group remaining uncoordinated. A pseudo-octahedral coordination sphere is completed by a bidentate bipy unit. The electronic nature of this complex is investigated by means of DFT calculations. (C) 2013 Elsevier B.V.
