摘要：

New ammonium derivatives of peroxo-carboxylato molybdenum(VI) complexes of general formula (NH4)(2)[MoO(O-2)(2)(HxL)](.)nH(2)O with L = oxalate (ox), citrate (cit), tartrate (tart), glycolate (glyc) and malate (mal) and (NH4)(2)[MoO2(O-2)(L)] with L = oxalate (ox) have been prepared and characterized on the basis of elemental and thermal analysis as well as by IR and C-13 NMR spectroscopy. These last two spectroscopic methods have been used to suggest the coordination mode of the ligand in the complexes. The X-ray crystal structures of the compounds (NH4)(2)[Mo2O2(O-2)(2)(OH)(2)(ox)(2)], (NH4)(2)[MoO(O-2)(2)(ox)] and (NH4)(2)[MoO(O-2)(2) (glyc)](.)0.5EtOH have been determined, all showing a sevenfold-coordinated Mo atom with bidentate peroxides and carboxylate ligands.
