Aqua­bis­(4-chloro­benz­yl)bis­(nicotinato-κ2O,O′)tin(IV)

In the title molecule, [Sn(C7H6Cl)2(C6H4NO2)2(H2O)], the O atoms of the two chelating nicotinate groups and the O atom of the coordinated water molecule comprise the pentagonal plane of the trans-C2SnO5 pentagonal–bipyramid [C—Sn—C = 178.62 (11) °] surrounding the SnIV atom. In the crystal, adjacent molecules are linked by O—H⋯N hydrogen bonds, generating a chain running along the body diagonal of the triclinic unit cell.

{[(N-Butyl-N-methylcarbamothioyl)sulfanyl]acetato-κO}tris(2-chloro­benz­yl)tin(IV)

The Sn atom in the title compound, [Sn(C7H6Cl)3(C8H14NO2S2)], is coordinated by three chlorobenzyl ligands and one carboxylate O atom of the substituted acetate ligand in a distorted tetrahedral environment. Three of the C atoms of the n-butyl group are disordered over two sites with equal occupancies.

catena-Poly[[tris­(4-fluoro­benz­yl)tin(IV)]{μ-[(N,N-diisopropylcar­bamo­thioyl)sulfanyl]acetato-κ2O:O′}]

In the title compound, [Sn(C7H6F)3(C9H16NO2S2)]n, the Sn atom is coordinated in a slightly distorted, trans-C3SnO2 trigonal-bipyramidal environment. Symmetry-related Sn atoms are bridged by diisopropyldithiocarbamoylacetato ligands, forming a one-dimensional polymer along [001].

Dichloridobis(4-chloro­benz­yl)(4,4′-dimethyl-2,2′-bipyridine-κ2N,N′)tin(IV)

The SnIV atom in the title compound, [Sn(C7H6Cl)2Cl2(C12H12N2)], is coordinated by the bidentate N-heterocycle molecule, two chlorobenzyl anions and two Cl− anions in a distorted trans-C2SnCl2N2 octahedral geometry [C—Sn—C = 178.4 (1)°]. In the molecular structure, the two benzene rings are oriented at a dihedral angle of 39.62 (17)°.

Tetra-chloridobis(dibenzyl sulfoxide-κO)tin(IV).

The six-coordinate SnIV atom in the title compound, [SnCl4(C14H14OS)2], exists in a cis-SnCl4O2 octahedral geometry. Of the four Cl atoms, two are close to adjacent S atoms [Cl⋯S = 3.320 (1) and 3.376 (1) Å]; the Sn—Cl bonds involving these two Cl atoms are longer than the other two Sn—Cl bonds.

Trichlorido(4-methyl­benz­yl)bis­(1H-pyrazole-κN2)tin(IV)

The six-coordinate SnIV atom in the title compound, [Sn(C8H9)Cl3(C3H4N2)2], shows an octahedral coordination. The N atoms of the N-heterocycle are cis to each other. The Sn—N bond that is trans to the Sn—C bond is shorter than the Sn—N bond trans to the Sn—Cl bond. Weak N—H⋯Cl hydrogen bonds link adjacent molecules, generating a double chain running along the c axis.

(2,2′-Bipyridine-κ2N,N′)dichloridobis(4-fluoro­benz­yl)tin(IV)

The six-coordinate SnIV atom in the title compound, [Sn(C7H6F)2Cl2(C10H8N2)], shows a trans-C2SnN2Cl2 octahedral coordination [C—Sn—C = 174.81 (10) and 176.71 (9)° in the two independent molecules in the asymmetric unit]; the Cl atoms are cis to each other as are the N atoms of the chelating N-heterocycle.

catena-Poly[[tribenzyl­tin(IV)]-μ-4-formyl-2-meth­oxy-6-nitro­phenolato-κ2O1:O4]

The formylmethoxynitrophenoxide ions in the polymeric title compound, [Sn(C7H7)3(C8H6NO5)]n, link adjacent triorganotin(IV) cations into linear chains lying close to (101) [Sn—O = 2.1227 (12) Å and Sn← O = 2.4936 (13) Å]. The SnIV atom is displaced out of the C3Sn girdle of the trans-C3SnO2 trigonal-bipyramidal polyhedron in the direction of the covalently-bonded O atom [Sn—O—C = 137.63 (11)°] by 0.247 (1) Å; the geometry is distorted towards an octahedron by a remote O atom of the methoxy subsituent [Sn⋯O = 3.019 (1) Å]

Bis{μ-2-[(N,N-diisopropyl­carbamothio­yl)sulfan­yl]acetato-κ2O:O′}bis­(bis­(4-chloro­benz­yl){2-[(N,N-diisopropyl­carbamothio­yl)sulfan­yl]acetato-κ2O,O′}tin(IV))

The dinuclear title complex, [Sn2(C7H6Cl)4(C9H16NO2S2)4], lies on a center of inversion. The SnIV atoms are chelated by one of the two carboxylate ions; the other carboxylate ion bridges two metal atoms. The geometry of the six-coordinate SnIV atom is a distorted trans-C2SnO4 octahedron [C—Sn—C = 155.32 (8)°].

Tris(2-chloro­benz­yl)[3-(4-methyl­phen­yl)prop-2-enoato-κO]tin(IV)

The SnIV atom in the title compound, [Sn(C7H6Cl)3(C10H9O2)], exists in a tetrahedral geometry [Σ C—Sn—C = 341.5 (4)°]. If the doubly bonded carbonyl O atom is taken into account for the coordination sphere of Sn [Sn⋯O = 2.808 (2) Å], the coordination geometry can be described as a cis-pentagonal bipyramid.
