?(2)-Oxalato-bis-[triphen-yl(thio-urea-?S)tin(IV)].

ABSTRACT: The asymmetric unit of the binuclear title compound, [Sn(2)(C(2)O(4))(C(6)H(5))(6)(CH(4)N(2)S)(2)], consists of one half of the organotin(IV) mol-ecule. The remainder is generated by a twofold rotation axis passing through the mid-point of the oxalate C-C bond. The Sn(IV) atom exhibits a distorted trigonal-bipyramidal coordination environment with the phenyl groups in equatorial positions and the thio-urea and the monodentately bridging oxalate anion in axial positions. The mol-ecules are linked through N-H?O hydrogen bonds involving the amino group of the thio-urea ligand and the uncoordinating oxalate O atoms, forming layers parallel to (001). Weak C-H?O inter-actions are also present.

Triphen-yl(pyrrolidine-1-carbodi-thio-ato-?S)tin(IV).

Project description: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 disordered over two sets of sites of equal occupancy. In the crystal, very weak C-H?S inter-actions link the mol-ecules into a three-dimensional network, with both S atoms acting as acceptors.

Di-chlorido-diphenyl-bis-(thio-urea-?S)tin(IV).

Project description:The title compound, [Sn(C6H5)2Cl2(CH4N2S)2], has been obtained from the reaction between Sn(C6H5)2Cl2 and SC(NH2)2. The asymmetric unit consists of one half of the mol-ecular unit, the remainder generated by a twofold rotation axis located along the Cl-Sn-Cl bonds. The Sn(IV) atom is coordinated by two phenyl groups, two Cl atoms and two thio-urea ligands in an all trans octa-hedral C2Cl2S2 environment. Individual mol-ecules are connected through N-H?Cl hydrogen bonds, leading to a three-dimensional network structure. Intra-molecular N-H?Cl hydrogen bonds are also present.

Di-?-hydroxido-bis-[dimeth-yl(thio-cyanato-?N)tin(IV)].

Project description:The Sn(IV) atom in the centrosymmetric title complex, [Sn2(CH3)4(NCS)2(OH)2], adopts a distorted trigonal-bipyramidal coordination environment defined by two methyl C atoms and one bridging hydroxide group in the equatorial plane while the other bridging hydroxide group and the N atom of the thio-cyanate anion are in the apical >positions. The dinuclear species are linked through O-H?S and C-H? S hydrogen-bonding inter-actions into a three-dimensional network.

Di-chlorido-dimethyl-bis-(thio-urea-?S)tin(IV).

Project description:The title compound, [Sn(CH3)2Cl2(CH4N2S)2], crystallizes with two half-mol-ecules in the asymmetric unit. Both mol-ecules are completed by inversion symmetry with the two Sn(IV) atoms located on inversion centers. The metal atoms have distorted octa-hedral coordination environments defined by two Cl atoms, two C atoms of methyl groups and two thio-urea S atoms. In the crystal, mol-ecules are linked via N-H?Cl and N-H?S hydrogen bonds, forming a three-dimensional structure.

Chloridodimeth-yl(thio-semi-carbazide)tin(IV) chloride.

Project description:In the title salt, [Sn(CH(3))(2)Cl(CH(4)N(3)S)]Cl, the Sn(IV) atom is five-coordinated in a distorted trigonal-bipyramidal geometry with two methyl groups and one S atom in the equatorial plane, and one N atom and one Cl atom occupying the apical positions. In the crystal, mol-ecules are linked by inter-molecular N-H?S hydrogen bonds with set graph-motif C(4) along [010]. N-H? Cl hydrogen bonds with graph-set motif D(2) and D(3) (3)(10) link cations and anions.

[?-1,2,3,4-Tetra-kis(pyridin-4-yl)butane-?(2) N (1):N (4)]bis-[trimeth-yl(thio-cyanato-?N)tin(IV)].

Project description:In the title compound, [Sn2(CH3)6(NCS)2(C24H22N4)], the 1,2,3,4-tetra-kis-(pyridin-4-yl)butane ligand uses the pyridine N atoms at the ends of the butyl chain to coordinate to two trimethylthiocyanatotin(IV) units, forming a dinuclear structure. The Sn(IV) atom in the mol-ecule shows a distorted trans-trigonal-bipyramidal coordination with the methyl groups in equatorial positions. The mol-ecule lies on a center of inversion, with the mid-point of the butyl chain coinciding with this symmetry element. In the crystal, weak C-H?? inter-actions occur between pyridine rings of adjacent mol-ecules.

1-Benzoyl-3,3-bis-(propan-2-yl)thio-urea.

Project description:Two independent thio-urea derivatives comprise the asymmetric unit of the title compound, C(14)H(20)N(2)OS. The major difference between the mol-ecules relates to a twist in the relative orientation of the benzene rings [torsion angles = 4.5?(2) and -19.9?(2)° for the two independent mol-ecules]. The thio-carbonyl and carbonyl groups lie to opposite sides of the mol-ecule as there are twists about the central N-S bond [torsion angles = 83.90?(15) and 81.77?(15)°]. Supra-molecular chains extending parallel to [101] with a stepped topology and mediated by N-H?O hydrogen bonding feature in the crystal structure. C-H?O and C-H?? inter-actions are also present.
