Crystal Structure and Properties of Potassium Hydroxostannate(IV) K2Sn(OH)6

A single-crystal X-ray investigation of potassium hydroxostannate(IV) K2Sn(OH)6 showed rhombohedral space group R3 with a = 6.545(1) Å and c = 12.808(3) Å. The Sn atom is surrounded by a slightly distorted octahedral array of six O atoms with Sn-O 2.068(1) Å. [Sn(OH)6]2- complex anions are linked by O-H⋯O hydrogen bonds 2.894(2) Å long. An X-ray diffraction powder pattern was indexed. IR absorption bands were assigned. Thermolysis of the hydroxostannate proceeds in three stages at 235, 362, and 495°C to split 2, 1/3, and 2/3 water molecules, respectively.
