Reaction of A 2 CO 3 (A = K, Rb) with Sn and Se in an H 2 O/CH 3 OH mixture at 115±130 °C affords the isotypic selenidostannates(IV) A 6 Sn 4 Se 11 ´x H 2 O (A = K, x = 8) 1 and 2 whose discrete [Sn 4 Se 11 ] 6± anions each contain two corner-bridged ditetrahedral [Sn 2 Se 6 ] 4± species. Similar re
