Nitrilotriacetato oxomolybdenum(V) dinuclear complex (NH4)4[cis-Mo2O4(nta)2] · 7H2O (1) (H3nta = nitrilotriacetic acid) and its incomplete cubane-type trinuclear molybdenum(IV) complex [Mo3O(OH)3(Hnta)3] · Cl · 3H2O (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 β-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 molybdenum(V) complexes based on 13C NMR observations in solution. © 2007 Elsevier B.V. All rights reserved.
