New dinuclear molybdenum(V) complexes with beta'-hydroxy-beta-enaminones containing 4-hydroxy-2-pyrone ring

New dinuclear molybdenum(V) complexes of the general formula [Mo_2O_4L_2D_2], have been prepared by the reaction of [Mo_2O_3(acac)_4] (acac = acetylacetonate ion) with the beta'-hydroxy-beta-enaminones (L). All prepared complexes consist of Mo_2O_4^2^+ cores coordinated by two ligands L via two donor oxygen atoms as in the analogous beta-diketonates. The usual octahedral coordination around the molybdenum atoms is completed by the monodentate solvent molecules D (methanol, ethanol or i-propanol). All compounds were characterized by elemental analyses, IR and one- and two-dimensional NMR spectra, thermal analysis and some of them by X-ray crystallography (1a, 4a, 8b and 9a
