摘要：
Nitrilotriacetato oxomolybdenum(V) dinuclear complex (NH4)(4)[cis-Mo2O4(nta)(2)] center dot 7H(2)O (1) (H(3)nta = nitrilotriacetic acid) and its incomplete cubane-type trinuclear molybdenum(IV) complex [Mo3O(OH)(3)(Hnta)(3)] center dot Cl center dot 3H(2)O (2) are isolated in a weak acidic and an acidic solutions, respectively (pH 4.5 and 1.0). The nitrilotriacetate ligand in the anion 1 or the cation 2 displays tridentate mode through the nitrogen atom and the oxygen atoms of beta-carboxy groups. Unusual protonations of bridged oxygen atoms in 2 have not effect on the skeleton of molybdenum(IV) cap Mo3O unit. There are obvious dissociations of molybdenurn(V) complexes based on C-13 NMR observations in solution. (c) 2007 Elsevier B.V. All rights reserved.
