Crystal and molecular structure of di-µ-phenoxo-bis[dichlorodiphenoxomolybdenum(V)]

Abstract

Crystals of the title complex are monoclinic, a= 12.279(4), b= 14.744(5). c= 10.579(3)Å. β= 107.14(2)°, space group P2₁/n, Z= 2. The intensities of 1 117 reflections collected on an automatic diffractometer have been used to refine the structure to R 0.047. The dimeric molecule, which has two molybdenum atoms bridged through two phenoxy-oxygen atoms, is located on a centre of symmetry. The molybdenum atoms are octahedrally co-ordinated, being bonded to two chlorine atoms [2.317(3) and 2.360(4)Å] and four phenoxy-oxygen atoms. two of which are terminal [1.806(7) and 1.822(8)Å] and two bridging [2.014(8) and 2.059(8)Å]. The Mo ⋯ Mo distance is 2.801(2)Å.
