Tris(2,4-dimethyl-benzene-thiol-ato)phenyl-tin(IV).

ABSTRACT: In the title compound, [Sn(C(6)H(5))(C(8)H(9)S)(3)], the Sn atom has an approximately tetra-hedral SNCS(3) geometry, with angles at this atom ranging from 105.13 (3) to 113.54 (9)°. The crystal packing does not involve any significant inter-molecular inter-actions, although the benzene rings are involved in a number of weak intra- and inter-molecular C-H⋯π inter-actions.

Project description:The asymmetric unit of the title complex, [Sn(CH(3))(2)(C(6)H(7)N(2)S)(2)], contains two independent mol-ecules with similar configurations. In each, the Sn(IV) cation is coordinated by two methyl and two 4,6-dimethyl-pyrimidine-2-thiol-ate anions in a distorted SnS(2)C(2) tetra-hedral geometry. In the two mol-ecules, the S-Sn-S bond angles are 87.70 (5) and 88.93 (4)°, while the C-Sn-C bond angles are 125.7 (3) and 125.9 (2)°. Weak C-H⋯N hydrogen bonding is present in the crystal structure.

Tris(2-chloro-benz-yl)(1H-1,2,4-triazole-5-thiol-ato-κS)tin(IV)-tris-(2-chloro-benz-yl)(4H-1,2,4-triazole-3-thiol-ato-κS)tin(IV) (1/1).

Project description:Tris(2-chloro-benz-yl)tin hydroxide condenses with 3-mercapto-1,2,4-triazole to form the 1:1 cocrystal of the title compound, [Sn(C(7)H(6)Cl)(3)(C(2)H(2)N(3)S)]. The asymmetric unit contains two mol-ecules which differ only in the position of the nitro-gen-bound H atom of the triazole ring; one mol-ecule is linked to the other mol-ecule by an N-H⋯N hydrogen bond. In the second mol-ecule, two of the chloro-benzyl units are disordered over two positions in a 0.73 (1):0.27 (1) ratio. The Sn atom in both mol-ecules shows a distorted tetra-hedral SnSC(3) coordination.

Dimethyl-bis(3-methylsulfanyl-1,2,4-thia-diazole-5-thiol-ato)tin(IV).

Project description:In the title compound, [Sn(CH(3))(2)(C(3)H(3)N(2)S(3))(2)], the Sn(IV) atom is coordinated within a C(2)N(2)S(2) donor set that defines a skew-trapezoidal bipyramidal geometry in which the methyl groups lie over the weakly coordinated N atoms. Two independent mol-ecules comprise the asymmetric unit, each of which lies on a mirror plane that passes through the C(2)Sn unit.

2,4-Dimethyl-N-phenyl-benzene-sulfonamide.

Project description:The asymmetric unit of the crystal structure of the title compound, C(14)H(15)NO(2)S, contains two mol-ecules. The conformations of the N-C bonds in the C-SO(2)-NH-C segments of the structure have trans and gauche torsion angles with the S=O bonds. Furthermore, the torsion angles of the C-SO(2)-NH-C groups in the two mol-ecules are 46.1?(3) (glide image of mol-ecule 1) and 47.7?(3)° (mol-ecule 2). The ortho-methyl groups in the sulfonyl benzene ring are oriented away from the S=O bonds. The two benzene rings are tilted relative to each other by 67.5?(1) and 72.9?(1)° in the two mol-ecules. N-H?O and C-H?O hydrogen bonds pack the mol-ecules into one-dimensional chains in different directions, resulting in a two-dimensional network.

Project description:In the title polymeric coordination compound, [Sn(CH(3))(3)(C(10)H(11)O(2))](n), the Sn atom has a distorted trigonal-bipyramidal coordination geometry, with two O atoms of two symmetry-related carboxyl-ate ligands in axial positions and three methyl groups in equatorial positions. In the crystal structure, carboxyl-ate bridges link the metal atoms, forming zigzag chains parallel to the b axis.

(Dimethyl sulfoxide-?O)di-phenyl-(3-thioxo-3H-1,2-dithiole-4,5-dithiol-ato-?S,S)tin(IV).

Project description:The Sn atom in the title compound, [Sn(C(6)H(5))(2)(C(3)S(5))(C(2)H(6)OS)], exists within a distorted trigonal-bipyramidal geometry defined by two S atoms of the 1,2-dithiole-3-thione-4,5-dithiol-ate dianion, two ipso-C atoms from the phenyl groups, and the O atom of the dimethyl sulfoxide mol-ecule. In this description, one of the S atoms and the O occupy axial positions. In the crystal, centrosymmetrically related mol-ecules associate via pairs of C-H?S contacts, forming dimeric aggregates.

Poly[tris-(2,5-dimethyl-benzene-1,4--dicarboxyl-ato)bis-(pyridine)trizinc(II)].

Project description:The asymmetric unit of the title polymeric compound, [Zn(3)(C(10)H(8)O(4))(3)(C(5)H(5)N)(2)](n) or [Zn(3)(dmbdc)(3)(py)(2)](n) (dmbdc = 2,5-dimethyl-benzene-dicarboxyl-ate; py = pyridine) contains two Zn(II) ions, one of which is located on an inversion centre, one and a half 2,5-dimethyl-benzene-dicarboxyl-ate ligands and one pyridine ligand. Each ZnO(6) octa-hedron is sandwiched between two ZnO(4)N square-pyramids, forming a trinuclear zinc secondary building unit (SBU); each SBU is further linked by six 2,5-dimethyl-benzene-dicarboxyl-ate ligands with six adjacent trinuclear zinc SBU's, forming a two-dimensional layer structure with a (3,6) net. One of the three zinc ions is octa-hedrally coordinated and the other two are square-pyramidally coordinated. The coordination modes for 2,5-dimethyl-benzene-dicarboxyl-ates are bis-(bidentate) or bidentate-tridentate.

Dichloridobis(pyridine-2-thiol-ato-κ²N,S)tin(IV): a new polymorph.

Project description:The title compound, [SnCl₂(C₅H₄NS)₂], is the product of reaction of 2,2'-dipyridyl disulfide with tin tetra-chloride. The Sn(IV) atom adopts a distorted octa-hedral geometry, with the two bidentate pyridine-2-thiol-ate ligands forming two planar four-membered chelate rings. The two Sn-Cl, two Sn-N and two Sn-S bonds are in cis, cis and trans configurations, respectively. The crystal grown from acetonitrile represents a new monoclinic polymorph in space group C2/c with the mol-ecule having twofold rotational symmetry, the Sn(IV) atom lying on the twofold axis. The mol-ecular structure of the monoclinic polymorph is very close to that of the triclinic polymorph studied previously in space group P-1, the mol-ecule occupying a general position [Masaki & Matsunami (1976 ▶). Bull. Chem. Soc. Jpn, 49, 3274-3279; Masaki et al. (1978 ▶). Bull. Chem. Soc. Jpn, 51, 3298-3301]. Apparently, the formation of the two polymorphs is determined by the different systems of inter-molecular inter-actions. In the crystal of the monoclinic polymorph, mol-ecules are bound into ribbons along the c axis by C-H⋯Cl hydrogen bonds, whereas in the crystal of the triclinic polymorph, mol-ecules form chains along the a axis by attractive S⋯S inter-actions. The crystal studied was a pseudo-merohedral twin; the refined BASF value is 0.221 (1).

Project description:The title compound, [Sn(C(10)H(13))(3)(C(7)H(4)ClO(2))], crystallized with two independent mol-ecules per asymmetric unit. In each mol-ecule, the Sn(IV) atom is four-coordinate and possesses a distorted tetra-hedral geometry. One of the phenyl rings of one molecule is equally disordered over two positions.
