(4-Hydroxy-methyl-1H-imidazole-κN)bis-(tri-tert-butoxy-silanethiol-ato-κO,S)cadmium(II).

Project description:The Cd(II) atom in the title compound, [Cd(C(12)H(27)O(3)SSi)(2)(C(4)H(6)N(2)O)], is penta-coordinated by two O and two S atoms from the O,S-chelating silanethiol-ate residue and one N from the 4-hydroxy-methyl-imidazole ligand and shows a strongly distorted trigonal-bipyramidal geometry. The title complex is isostructural with its zinc analog. The hydroxy group of the ligand is involved in intra-molecular O-H⋯S hydrogen bonding and also acts as an acceptor in the formation of an inter-molecular N-H⋯O hydrogen bond, which links mol-ecules of the complex into zigzag chains parallel to the b axis. One of the tert-butyl groups is disordered over two orientations with occupancies of 0.557 (12):0.443 (12).

μ-4,4'-Bipyridyl-1:2κN:N'-methanol-2κO-tetrakis(tri-tert-butoxy-silanethiol-ato)-1κO,S;2κS-dizinc(II).

Project description:The title compound, [Zn(2)(C(12)H(27)O(3)SSi)(4)(C(10)H(8)N(2))(CH(4)O)], is a binuclear complex with the two Zn(II) atoms linked via a bridging 4,4'-bipyridyl ligand. One of the Zn(II) atoms is penta-coordinated by two O,S-chelating tri-tert-butoxy-silanethiol-ate units and one N atom of a 4,4'-bipyridine ligand, and the other Zn(II) atom is tetra-hedrally coordinated by two tri-tert-butoxy-silanethiol-ate anions acting as monodentate S ligands, the methanol O atom and the other N atom of the 4,4'-bipyridine ligand. This non-symmetrical coordination induces twisting and bending in the 4,4'-bipyridine ligand and introduces chirality into the system. The crystal studied exhibits inversion twinning. One tert-butyl group is disordered approximately equally over two positions.

Tetra-n-butyl-ammonium iodido(pyrrolidine-1-carbodithio-ato-?S,S')(tris-tert-butoxy-silanethiol-ato-?S)cadmate(II).

Project description:In the anion of the title compound, (C(16)H(36)N)[Cd(C(5)H(8)NS(2))(C(12)H(27)O(3)SSi)I], the Cd atom is four-coordinated by S,S'-chelating dithio-carbamate, S-donating silanethiol-ate and iodide ligands in a distorted tetrahedral environment . Inter-molecular C-H? S and C-H?I inter-actions between cations and anions are present. Two C atoms of a tert-butyl group are disordered over two positions; the site occupancies are ca 0.65 and 0.35.

(1,2,3,4-Tetra-hydro-isoquinoline-2-carbo-dithio-ato-κS,S')(thio-cyanato-κN)(tri-phenyl-phosphane)nickel(II).

Project description:The Ni(II) atom in the mononuclear title compound, [Ni(C(10)H(10)NS(2))(NCS)(C(18)H(15)P)], exists within a S(2)PN donor set that defines a distorted square-planar geometry. A significant asymmetry in the Ni-S bond lengths support the less effective trans effect of SCN(-) over PPh(3).

Bis-(3-tert-butyl-pyridine-κN)bis-(4-tert-butyl-pyridine-κN)bis(thio-cyanato-κN)cadmium.

Project description:The asymmetric unit of the title compound, [Cd(NCS)(2)(C(9)H(13)N)(4)], consists of one Cd(II) cation located on a centre of inversion, one thio-cyanate anion, one 3-tert-butyl-pyridine ligand and one 4-tert-butyl-pyridine ligand in general positions. The tert-butyl group of the 4-tert-butyl-pyridine ligand is disordered over two sets of sites in a 0.25:0.75 ratio and was refined using a split model. The Cd(II) cation is coordinated by six N atoms of four tert-butyl-pyridine ligands and two N-bonded thio-cyanate anions within a slightly distorted octa-hedral coordination environment.

Bis(N-sec-butyl-N-n-propyl-dithio-carbamato-κS,S')(1,10-phenanthroline-κN,N')zinc(II).

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).

(μ-2-Pyridine-aldazine-κN,N':N'',N''')bis-[bis-(N,N-di-n-propyl-dithio-carbamato-κS,S')cadmium(II)].

Project description:The dinuclear centrosymmetric title compound, [Cd(2)(C(7)H(14)NS(2))(4)(C(12)H(10)N(4))], features a tetra-dentate 2-pyridine-aldazine ligand that chelates two Cd centres. The coordination geometry for Cd is distorted octa-hedral based on a cis-N(2)S(4) donor set. In the crystal structure, mol-ecules are connected into a supra-molecular chain aligned along the a direction via C-H⋯S and C-H⋯π contacts, and by π-π contacts [centroid-to-centroid distance 3.5708 (15) Å]. The n-propyl groups are each disordered, one equally over two sites and the other with a site-occupancy factor of 0.618 (8) for the major component.

Trans-bis-(3-tert-butyl-pyridine-κN)bis-(4-tert-butyl-pyridine-κN)bis-(thio-cyanato-κN)manganese(II).

Project description:The asymmetric unit of the title compound [Mn(NCS)(2)(C(9)H(13)N)(4)] consists of one Mn(II) cation located on a center of inversion, one thio-cyanato anion, one 3-tert-butyl-pyridine ligand and one 4-tert-butyl-pyridine ligand in general positions. The tert-butyl group of the 4-tert-butyl-pyridine ligand is disordered over two sets of sites in a 0.60:0.40 ratio. The Mn(II) cation is coordinated by six N atoms of four tert-butyl-pyridine ligands and two N-bonded thio-cyanato anions within a slightly distorted octa-hedral coordination environment.
