The title mol-ecule, [Sn(C(8)H(3)F(6))(4)], lies on a twofold rotation axis with the Sn(IV) ion in a distorted tetra-hedral coordination environment. Both -CF(3) groups attached to one of the unique benzene rings are disordered over two sets of sites, with the ratios of refined occupancies being 0.719 (14):0.281 (14) and 0.63 (5):0.37 (5).

The crystal structure of the title salt, [Sn(C(7)H(7))(3)(C(18)H(15)AsO)(2)][B(C(6)H(5))(4)], consists of discrete cations and anions; the tin atom of the cation is five-coordinated in a distorted trans-C(3)SnO(2) trigonal-bipyramidal geometry [summation of C-Sn-C angles 360.0 (3)° and O-Sn-O angle 173.1 (1)°]. The structure contains voids of 113 (19) Å(3), but no solvent mol-ecule could reason...

In the title compound, [Sn(C6H5)3(C5H8NS2)], the Sn(IV) atom adopts a distorted SnC3S tetra-hedral coordination geometry [spread of bond angles = 94.43 (7)-120.74 (7)°]. A short intra-molecular Sn⋯S contact [3.0270 (9) Å] occurs and two intra-molecular C-H⋯S inter-actions help to establish the conformation. Three of the methyl-ene groups of the pyrrolidine-1-carbodi-thio-ate ligand are disorder...

In the title tribenzyl-chloridotin-triphenyl-phosphine adduct, [Sn(C(7)H(7))(3)Cl(C(18)H(15)OP)], the Sn(IV) atom is in a trans-C(3)SnClO trigonal-bipyramidal geometry and is displaced out of the C(3)Sn girdle in the direction of the axial Cl atom by 0.112 (1) in one independent mol-ecule and by 0.167 (1) Å in the other. The phenyl ring of one of the six benzyl units was refined as equally diso...

The mol-ecule of the title compound, [Sn(C(5)H(5)S)(4)], lies on a special position of site symmetry. The Sn(IV) atom shows a slightly distorted tetra-hedral coordination.
