ABSTRACT: In the title compound, [Zn(C(8)H(16)NS(2))(2)], the Zn(II) atom is chelated by two S,S'-bidentate dithio-carbamate ions in a very distorted tetra-hedral geometry. The alkyl chains of the ligands are equally disordered over two sets of sites.
Project description:The complete mol-ecule of the title compound, [Zn(C(4)H(8)NS(2))(2)(C(10)H(8)N(2))], is generated by crystallographic twofold symmetry, with the Zn atom lying on the rotation axis; the axis also bis-ects the central C-C bond of the 2,2'-bipyridine mol-ecule. The metal atom is chelated by two S,S'-bidentate dithio-carbamate anions and the N,N'-bidentate heterocycle, resulting in a distorted cis-ZnN(2)S(4) octa-hedral geometry. The methyl and ethyl groups of the anion are statistically disordered.
Project description:In the title compound, [Zn(2)(C(22)H(36)NS(2))(4)], two bidentate dithio-carbamate groups chelate directly to the Zn(II) atoms, whereas the two remaining dithio-carbamate ligands bridge the Zn atoms via a crystallographic inversion centre. The Zn atoms show a strongly distorted tetra-hedral geometry. Adding the long S?S distance with the inversion centre being in the middle, the resulting five-coordinate geometry around the Zn atoms can be considered to be between distorted recta-ngular pyramidal and trigonal bipyramidal, with a calculated ? value of 0.31. In this dimer complex, two inversion-related tetra-decyl carbon chains exhibit all-trans conformations, and the other two chains show a cis conformation at the end of the chains.
Project description:The title dinuclear Zn(II) complex, [Zn(2)(C(3)H(6)NS(2))(4)(C(10)H(8)N(2))], is centrosymmetric; the mid-point of the C-C bond linking the two pyridine rings is located on an inversion center. The pyridine N atom coordinates to the Zn(II) cation, which is also chelated by two dimethyl-dithio-carbamate anions, giving a trigonal-bipyramidal ZnNS(4) geometry. Weak inter-molecular C-H?S hydrogen bonding is present in the crystal structure.
Project description:In the title compound, [Cu(C(5)H(10)NO(2)S(2))(2)], the Cu(II) cation is chelated by two bis-(2-hydroxy-ethyl)dithio-carbamate anions with a distorted square-planar coordination geometry. Inter-molecular O-H?O hydrogen bonding is observed between the terminal hydr-oxy groups in the crystal structure.
Project description:Two independent but very similar mol-ecules comprise the asymmetric unit of the title compound, [Zn(C(8)H(16)NS(2))(2)(C(12)H(8)N(2))]. The N(2)S(4) donor set about Zn is defined by two symmetrically chelating dithio-carbamate ligands and a 1,10-phenanthroline ligand. Distortions from the ideal octa-hedral coordination geometry arise from the restricted bite angles of the ligands. The main feature of the crystal packing is the formation of tetra-meric supra-molecular aggregates mediated by C-H?S inter-actions. Disorder was found in each of the sec-butyl groups. This was resolved over two positions in each case with the major components of the disorder having site occupancies in the range 0.551?(6)-0.725?(5).
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.
Project description:The copper(II) atom in the title compound, [Cu(C(5)H(10)NS(2))I(C(12)H(8)N(2))], is chelated by the N-heterocycle and the dithio-carbamate anion in a slightly distorted tetragonal coordination. The tetragonal-pyramidal coorination is completed by the iodine atom in the apical position. One ethyl group is disordered over two positions with site occupancies of 0.31?(2) and 0.69?(2).
Project description:The Zn(II) atom in the title compound, [Zn(C(5)H(10)NS(2))(2)(C(12)H(8)N(2))], exists in a distorted cis-octa-hedral N(2)S(4) donor set defined by two chelating dithio-carbamate anions as well as a 1,10-phenanthroline ligand. Each of the ligands coordinates in a symmetric mode. The crystal packing is stabilized by weak C-H?S, C-H??(ZnS(2)C) and ?-? [ring centroid distance between centrosymmetrically related pyridyl rings = 3.5955?(13)?Å] inter-actions.
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?? inter-actions.
Project description:The title compound, [Sb(C(5)H(10)NS(2))(3)], was synthesized from Sb(2)O(3), diethyl-amine, carbon dis-ulfide, hydro-chloric acid and sodium hydroxide. The structure has been published previously but H atoms were not included in the model [Raston & White (1976 ?). Chem. Soc. Dalton Trans. p. 791]. The current determination has significantly higher precision than the original work. The complex has three ligands. The Sb atom is coordinated by three bidentate diethyl-dithio-carbamate groups, two in an almost planar fashion and the third perpendicular to that plane with a dihedral angle of 86.429?(13)°. One ethyl group is disordered over two positions of equal occupancy.
