Abstract
Abstract Single crystals of Ag2 SrMnV2O8 have been prepared by reactions of metallic silver and a mixture of SrCO3, MnCO3 · H2O and V2O5. X-Ray investigations showed monoclinic symmetry, space group C6 2h -C2/c, a = 9.7022(9), b = 5.5882(5), c = 13.894(1), β = 90.41(1)°, Z = 4. The crystal structure is isotypic to Na2BaCuV2O8 and includes VO4 tetrahedra, MnO6 octahedra as well as irregular AgO8 and SrO10 polyhedra. Ag2SrMnV2O8 is characterized by a [MnV2O8] network incorporating Ag+ and Sr2+ or a [Ag2V28] frame incorporating Mn2+ and Sr2+ ions. Ag+ is able to replace an alkali ion in the cationic part of the crystal structure.
