The structure of tin(II) thiocyanate

Abstract

The structure of the title compound has been solved with three-dimensional X-ray diffraction data and refined to R 0.068. The crystals are triclinic, with space group P[1 with combining macron], and a= 5.665(4), b= 4.924(5), c= 10.242(9)Å, α= 83.13(7), β= 79.38(7), γ= 93.33(7)°, and Z= 2. Tin is surrounded by nine thiocyanate groups with Sn-N and Sn-S distances ranging from 2.20 to 3.85 and 2.837 to 3.738 Å respectively. The primary co-ordination of Sn involves only a subset of these contacts. Pyramidal co-ordination is achieved with Sn-N contacts of 2.20 and 2.27 Å and an Sn-S contact of 2.837 Å, the Sn lone pair completing a very distorted tetrahedron. inclusion of two further Sn-S contacts (3.111 and 3.335 Å) gives distorted octahedral co-ordination. The co-ordination of Sn in the thiocyanate is, therefore, entirely analogous to that encountered in the simple orthorhombic tin(II) halides -(PbCl2 structure).
