Abstract
Single crystals of SnAl2OCl6 were obtained from the educts SnCl2 and AlCl3 (obviously containing an oxidic impurity) in silica ampoules with the aid o f the Bridgman technique. According to single-crystal structure analysis. S nAl2Cl6 crystallizes with the monoclinic system (P2(1)/n, Z = 4, a = 942.3( 2), b = 1225.8(2), c = 948.4(3) pm, beta = 96.42(2)degrees). Characteristic structural features are centrosymmetric tetramers [Al4O2Cl10] and [(SnCl2/ 2Cl5)(2)] dimers which are connected via common edges, finally building up a three-dimensional structure.
