Abstract

Synthetic Cs(VO2)(3)(TeO3)(2) is built up from infinite sheets of distorted octahedral (VO6)-O-V groups, sharing vertices. These octahedral layers are "capped" by Te atoms (as parts of pyramidal [(TeO3)-O-IV](2-) groups) on both faces of each V/O sheet. with inter-layer, 12-coordinate, Cs+ cations providing charge compensation. CS(VO2)(3)(TeO3)(2) is isostructural with M(VO2)(3)(SeO3)(2) (M=NH4, K). Crystal data: Cs(VO2)(3)-(TeO3)(2), M-r = 732.93, hexagonal, space group P6(3) (No. 173), a = 7.2351(9) Angstrom, c = 11.584(2) Angstrom, V = 525.1(2) Angstrom(3), Z = 2, R(F) = 0.030, M wR(F-2)= 0.063.
