Abstract
Single crystals of Ba-2(VO)V2O8 have been prepared by solid state reac tions of Ba2V2O7, V2O3 and V2O5 in sealed silica tubes. This compound crystallizes with monoclinic symmetry, space group C 2/2-P2(1), a = 8. 1174(9), b = 5.9699(9), c = 9.2903(9) Angstrom, beta = 113.94(1)degree s, Z = 2. V5+ shows tetrahedral coordination. V4+ inside infinity 1[V( 3)O-4] chains is characterized by a square pyramidal coordination with a short apical V-O distance of 1.6 Angstrom typically for vanadyl gro ups. Ba2(VO)V2O8 represents a new structure type and is not isotypic t o Sr-2(VO)V2O8.
