Synthesis and structure of Mo3O9.4DMSO (DMSO = dimethyl sulphoxide): a novel chain structure
Abstract
The reaction of MoO3.2H2 with DMSO (dimethyl sulphoxide) in a DMSO–H2O solution produces the crystalline compound Mo3O9.4DMSO which has been shown by X-ray diffraction to consist of infinite chains of molybdenum–oxygen polyhedra; the chemical repeat unit of the chain contains one tetrahedron [Mo(Ot)2(Ob)2] which bridges two octahedra [Mo{cis(Ot)2}(Ob)2(DMSO)2], where Ot and Ob represent terminal and bridging oxo-ligands, respectively.
