New dinuclear molybdenum(V) complexes of the general formula [Mo 2 O 4 L 2 D 2 ], were prepared by the reaction of [Mo 2 O 3 (acac) 4 ] (acac = acetylacetonate ion) with β ′ ‐hydroxy‐β‐enaminones (L). All prepared complexes consist of Mo 2 O 4 2+ cores coordinated by two ligands L via two donor oxygen atoms as in the analogous β‐diketonates. The usual octahedral coordination around the molybdenum atoms is completed by the monodentate solvent molecules D (methanol, ethanol, or 2‐propanol). All compounds were characterized by elemental analyses, IR, one‐ and two‐dimensional NMR spectra, and thermal analysis, and some of them by X‐ray crystallography ( 1a , 4a , 8b , and 9a ).
