Na 6 Sn 4 Se 11 ´22 H 2 O can be crystallised at ±8 °C as yellow-orange needles from the 1 : 2 H 2 O/CH 3 OH mother liquor of a superheated reaction mixture of NaOH(s), Sn and Se. The bicyclic [Sn 4 Se 11 ] 6± anion exhibits crystallographic C 2 symmetry and is composed of corner-bridged SnSe 4 tetr
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
