Crystal and molecular structure of chloro(ethyl L-cysteinato-N,S) dimethyltin (IV)

Orthorhombic crystals of the title compound, C₇H₁₆ClNO₂SSn, belong to space groupP2₁2₁2₁, witha = 6.658(5),b = 10.974(3),c = 17.144(5) Å, andZ = 4. The diffractometer data, measured with CuK radiation, has been refined to anR index of 0.053 for 1110 observed terms. The geometry about the Sn atom in the monomeric complex units is distorted trigonal bipyramidal; the N and Cl atoms are in the apical positions, and the Sn lies at 0.107(1) Å from the equatorial plane. The Sn-Cl, Sn-S, and Sn-N bonds have lengths 2.523(4), 2.413(3), and 2.434(12) respectively, and the angle N-Sn is 166.9(3) °.
