Di-tert-butyl-bis(N-isopropyl-N-methyl-dithio-carbamato-κS,S')tin(IV).

ABSTRACT: The dithio-carbamate anions in the title compound, [Sn(C(4)H(9))(2)(C(5)H(10)NS(2))(2)], chelate to the Sn(IV) atom, which is six-coordinated in a skew-trapezoidal-bipyramidal geometry. The mol-ecule lies across a twofold rotation axis. The crystal studied was a non-merohedral twin, the ratio of the twin components being 0.82 (1):0.18 (1).

Bis(N-benzyl-N-isopropyl-dithio-carbamato-κS)di-n-butyl-tin(IV).

Project description:The Sn atom in the title compound, [Sn(C(4)H(9))(2)(C(11)H(14)NS(2))(2)], exists in a tetra-hedral C(2)S(2)Sn coordination geometry. The geometry is distorted towards skew-trapezoidal-bipyramidal owing to the proximity of the double-bonded S atoms. The C(2)Sn angles range from 129.0 (2) to 136.9 (2)°, the covalent Sn-S lengths from 2.529 (1) to 2.544 (1) Å, and the dative Sn←S lengths from 2.831 (1) to 3.042 (1) Å in the five independent mol-ecules comprising the asymmetric unit. Two of the butyl groups were modelled over two positions of equal occupancy. All butyl groups were refined with distance restraints.

Di-n-butyl-bis(N-n-butyl-N-ethyl-dithio-carbamato-κS)tin(IV).

Project description:The Sn atom in the title compound, [Sn(C(4)H(9))(2)(C(7)H(14)NS(2))(2)], exists in a tetra-hedral C(2)S(2)Sn coordination geometry. The geometry is distorted towards skew-trapezoidal-bipyramidal owing to the proximity of the double-bond S atoms [Sn-S = 2.521 (2) and Sn⋯S = 2.933 (2) Å]. The Sn atom lies on a special position of mm2 site symmetry and the tin-bound n-butyl chain is disordered about a mirror plane. The ethyl and n-butyl groups of the dithio-carbamate unit are disordered about another mirror plane.

Di-n-butyl-bis-(N-ethyl-N-phenyl-dithio-carbamato-κS)tin(IV).

Project description:The title compound, [Sn(C(4)H(9))(2)(C(9)H(10)NS(2))(2)], features a tetra-hedrally coordinated Sn(IV) atom; the dithio-carbamate ligands coordinate in a monodentate fashion, accompanied by two n-butyl chains. The non-coordinating thione S atoms are each proximate to the Sn(IV) atom [3.0136 (7) and 2.9865 (8) Å], giving rise to distortions from the ideal geometry as evident in the wide C-Sn-C bond angle of 139.06 (12) °. In the crystal, C-H⋯S inter-actions lead to the formation of a linear supra-molecular chain along the b axis. The chains are aligned into layers by C-H⋯π inter-actions, and the layers stack along [001]. One of the ethyl groups is statistically disordered over two sets of sites.

Di-tert-butyl-chlorido(N,N-dibenzyl-dithio-carbamato)tin(IV).

Project description:The Sn(IV) atom in the title diorganotin dithio-carbamate, [Sn(C(4)H(9))(2)(C(15)H(14)NS(2))Cl], is penta-coordinated by an asymmetrically coordinating dithio-carbamate ligand, a Cl atom and two C atoms of the Sn-bound tert-butyl groups. The resulting C(2)ClS(2) donor set defines a coordination geometry inter-mediate between square pyramidal and trigonal bipyramidal with a slight tendency towards the former.

Di-tert-butyl-chlorido(pyrrolidine-1-dithio-carboxyl-ato-κS,S')tin(IV).

Project description:The title compound, [Sn(C(4)H(9))(2)(C(5)H(8)NS(2))Cl], contains two mol-ecules in the asymmetric unit, with similar conformations. In both mol-ecules, the Sn atom adopts a distorted trigonal-bipyramidal geometry arising from two C atoms, one Cl atom and two S atoms from the bidentate dithio-carbamate ligand, with one Sn-S bond much longer than the other. One C atom of the pyrrolidine ring is disordered equally over two sites.

(N-sec-Butyl-N-n-propyl-dithio-carbamato-κS,S')triphenyl-tin(IV).

Project description:The Sn atom in the title compound, [Sn(C(6)H(5))(3)(C(8)H(16)NS(2))], is penta-coordinated by two S atoms, derived from an asymmetrically coordinating dithio-carbamate ligand, and three ipso-C atoms. The coordination geometry is inter-mediate between square-pyramidal and trigonal-bipyramidal, with a leaning towards the latter. The presence of close intra-molecular C-H⋯S contacts preclude the S atoms from forming significant inter-molecular inter-actions. Rather, mol-ecules are consolid-ated in the crystal structure by C-H⋯π inter-actions.

Di-n-butyl-bis-(N-cyclo-hexyl-N-ethyl-dithio-carbamato-?S,S')tin(IV).

Project description:The Sn(IV) atom in the title compound, [Sn(C(4)H(9))(2)(C(9)H(16)NS(2))(2)], is chelated by the two dithio-carbamate ions in a six-coordinate skew-trapezoidal-bipyramidal geometry. The two butyl groups are disordered over two positions in a 1:1 ratio.

(N-Benzyl-N-ethyl-dithio-carbamato)di-tert-butyl-chloridotin(IV).

Project description:The Sn(IV) atom in the title diorganotin dithio-carbamate, [Sn(C(4)H(9))(2)Cl(C(10)H(12)NS(2))], is penta-coordinated by an asymmetrically coordinating dithio-carbamate ligand, a Cl and two C atoms of the Sn-bound tert-butyl groups. The resulting C(2)ClS(2) donor set defines a coordination geometry inter-mediate between square pyramidal and trigonal bipyramidal with a slight tendency towards the former. In the crystal structure, C-H⋯π contacts link centrosymmetrically related mol-ecules into dimeric aggregates.

(N-Benzyl-N-isopropyl-dithio-carbamato)chloridodiphenyl-tin(IV).

Project description:The Sn(IV) atom in the title organotin dithio-carbamate, [Sn(C(6)H(5))(2)(C(11)H(14)NS(2))Cl], is penta-coordinated by an asymmetrically coordinating dithio-carbamate ligand, a Cl and two ispo-C atoms of the Sn-bound phenyl groups. The resulting C(2)ClS(2) donor set defines a coordination geometry inter-mediate between square-pyramidal and trigonal-bipyramidal with a slight tendency towards the latter. The formation of close intra-molecular C-H⋯Cl and C-H⋯S contacts precludes the Cl and S atoms from forming significant inter-molecular contacts. The presence of C-H⋯π contacts leads to the formation of supra-molecular arrays that stack along the b axis.

(N-Butyl-N-phenyl-dithio-carbamato-?S)triphenyl-tin(IV).

Project description:The title compound, [Sn(C(6)H(5))(3)(C(11)H(14)NS(2))], features a tetra-hedrally coordinated Sn atom, as the dithio-carbamate ligand coordinates in a monodentate fashion. Due to the proximity of the non-coordinating thione S atom, distortions from ideal tetra-hedral geometry about the metal atom are evident with the widest C-Sn-S angle being 117.26?(5)°. In the crystal, mol-ecules are linked by C-H?S inter-actions, which generate helical supra-molecular chains along the b axis.
