title: Di-μ(2)-chlorido-dichloridoocta-methyldi-μ(3)-oxido-tetra-tin(IV) bis[chloridodimeth-yl(pyrrolidine-1-carbodithio-ato-κ(2)S,S')tin(IV)].
abstract: In the title co-crystal, [Sn(4)(CH(3))(8)Cl(4)O(2)]·2[Sn(CH(3))(2)Cl(C(4)H(8)NS(2))], all the Sn(IV) atoms are in distorted trigonal-bipyramidal environments. In the mononuclear species, the carbodithio-ate ligand is unsymmetrically coordinated to the Sn(IV) atom, with Sn-S distances of 2.6722 (12) and 2.4706 (11) Å. All atoms with the exception of the methyl groups and one of the pyrrolidine ring CH(2) groups lie on a crystallographic mirror plane. The pyrrolidine ring exhibits an envelope conformation; the C atom at the flap is disordered above and below the plane of symmetry with fixed occupation factors of 0.50. The centrosymmetric dimer species consists of a central Sn(2)O(2) unit with two adjacent Sn(2)OCl four-membered rings.
