THE CRYSTAL AND MOLECULAR-STRUCTURES OF THE COMPOUNDS [CL4-XSN(CO(CO)4)X] WITH X = 1, 2 AND 3

The crystal structures of the compounds [Cl3SnCo(CO)4] 1, [Cl2Sn{Co(CO)4}2] 2, and [ClSn{Co(CO)4}3] 3, have been determined by X-ray crystallography. Sn is co-ordinated tetra-hedrally by Cl- and Co-substituents, the co-ordination polyhedron of Co is a distorted trigonal bipyramid. The Sn-Cl- and the Sn-Co-distances both increase from 1 to 3 (Sn-Co: 247.7 in 1, 253.2 in 2, and 260.6 pm in 3).
