Notes. Preparation and crystal structure of hexa-µ-acetato-dichlorodi-µ3-oxotetraoxotetramolybdenum(V)–acetic anhydride (1/1)

Abstract

Crystals of the title complex are monoclinic, with a= 14.992(5), b= 12.720(4), c= 17.536(6)Å, β= 101.46(2)° space group C2/c, and Z= 4. The intensities of 4 603 reflections collected on an automatic diffractometer have been used to solve and refine the structure to R 0.036. The tetranuclear complex molecule, which has four molybdenum atoms bridged through two oxo-groups and six bidentate acetato-ligands, is located on a two-fold axis. Two of the four molybdenum atoms have Mo–Mo 2.609 Å.
