摘要：

(Hmorph)(6)[Mo4V5O27] Cl.H2O (morph = morpholine) has been synthesized from ammonium vanadate and sodium molybdate in acidic aqueous solution by adding morpholine and its structure determined by single-crystal X-ray analysis. The structure of the molybdovanadate anion is a hybrid of the decavanadate structure in the vanadium-rich region and of the beta-octamolybdate structure in the molybdenum-rich region. It is built up of nine edge-sharing MO(6) octahedra, but with a random distribution of molybdenum and vanadium atoms in two ''capping'' metal atom sites in the vanadium-rich region.
