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

ABSTRACT: The title compound, [Sn(C(6)H(5))(3)(C(9)H(10)NS(2))], has two independent mol-ecules in the asymmetric unit and each features a tetra-hedrally coordinated Sn(IV) atom as the dithio-carbamate ligand coordinates in a monodentate fashion. As the non-coordinating thione S atom is proximate to the Sn atom [Sn?S(thione) = 3.1477?(6) and 2.9970?(5)?Å for the independent mol-ecules], distortions from the ideal geometry are evident [the widest angle being 120.48?(5)°]. The most notable feature of the crystal packing is the formation of C-H?? inter-actions that lead to the formation of supra-molecular layers parallel to ([Formula: see text]2[Formula: see text]).

The title compound, [Sn(C(6)H(5))(3)(C(9)H(10)NS(2))], has two independent mol-ecules in the asymmetric unit and each features a tetra-hedrally coordinated Sn(IV) atom as the dithio-carbamate ligand coordinates in a monodentate fashion. As the non-coordinating thione S atom is proximate to the Sn atom [Sn⋯S(thione) = 3.1477 (6) and 2.9970 (5) Å for the independent mol-ecules], distortions from the ideal geometry are evident [the widest angle being 120.48 (5)°].

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.

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.

(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-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.

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-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.

Crystal structures and Hirshfeld surface analyses of (N-hexyl-N-methyl-dithio-carbamato-κ2S,S')triphenyl-tin(IV) and [N-methyl-N-(2-phenyl-ethyl)-dithio-carbamato-κ2S,S']tri-phenyl-tin(IV).

Project description:The crystal and mol-ecular structures of two tri-phenyl-tin di-thio-carbamate compounds, viz. [Sn(C6H5)3(C8H16NS2)], (I), and [Sn(C6H5)3(C10H12NS2)], (II), are described. The di-thio-carbamate ligand in each mol-ecule coordinates in an asymmetric fashion resulting in heavily distorted tetra-hedral C3S coordin-ation geometries for the Sn atoms, with the distortions traced to the close approach of the non-coordinating thione-S atom. The mol-ecular packing in both compounds features C-H⋯π(Sn-phen-yl) inter-actions. In (I), the donors are Sn-phenyl-C-H groups leading to centrosymmetric aggregates, while in (II), the donors are both Sn-phenyl-C-H and methyl-C-H groups leading to supra-molecular chains propagating along the b axis. The identified aggregates assemble into their respective crystals with no directional inter-actions between them. An analysis of the Hirshfeld surfaces show distinctive patterns, but an overwhelming predominance (>99% in each case) of H⋯H, C⋯H/H⋯C and S⋯H/H⋯S contacts on the respective Hirshfeld surface.

Redetermination of tetra-kis(N,N-diethyl-dithio-carbamato)tin(IV).

Project description:The crystal structure of the title compound, [Sn(C(5)H(10)NS(2))(4)], was originally determined by Harreld & Schlemper [Acta Cryst. (1971), B27, 1964-1969] using intensity data estimated from Weissenberg films. In comparison with the previous refinement, the current redetermination reveals anisotropic displacement parameters for all non-H atoms, localization of the H atoms, and higher precision of lattice parameters and inter-atomic distances. The complex features a distorted S(6) octa-hedral coordination geometry for tin and a cis disposition of the monodentate dithio-carbamate ligands.

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.
