摘要

A ETS-10-like topological vanadoarsenate [NH4VO(AsO4)](n) 1 has been hydrothermally synthesized and structurally characterized by X-ray diffraction. The molecule structural analysis reveals that 1 is constructed by helical [-V-O-](n) chains and AsO4 tetrahedra. Crystal data for 1: Orthorhombic, with space group Pnna, a = 13.212(3) , b = 10.753(2) , c = 6.6266(13) , V = 941.4(3) (3), Z = 8, R-1 = 0.0515 and wR(2) = 0.1144.
