Sažetak
New dinuclear molybdenum(V) complexes have been obtained by the reaction of [Mo2O3(acac)4] (acac=acetilacetonate ion) with the polydentate ligands, β′-hydroxy-β-enaminones. All prepared complexes consist of Mo2O4 2+ core coordinated by two ligands as in the β-diketonates only through two donor oxygen atoms. Such bonding gives the opportunity for the sixth coordination place around molybdenum to be completed by the monodentate solvent molecule D. All compounds have been characterized by means of elemental analyses, one- and two-dimensional NMR spectroscopy, IR spectroscopy as well as by thermal analyses. The molecular and crystal structures of the molybdenum(V) complexes 1a and 1b coordinated by two different isomeric ligands as well as of the isomer a itself have been determined by a single crystal X-ray diffraction method.
