Tetra-μ3-iodido-tetra-kis-[(tri-n-butyl-phosphane-κP)copper(I)].

Project description:The title complex, [Cu4I4(C12H27P)4], crystallizes with six mol-ecules in the unit cell and with three independent one-third mol-ecule fragments, completed by application of the relevant symmetry operators, in the asymmetric unit. The tetranuclear copper core shows a tetrahedral geometry (site symmetry 3..). The I atoms also form a tetra-hedron, with I⋯I distances of 4.471 (1) Å. Both tetra-hedra show an orientation similar to that of a pair of self-dual platonic bodies. The edges of the I-tetra-hedral structure are capped to the face centers of the Cu-tetra-hedron and vice versa. The Cuface⋯I distances are 2.18 Å (averaged) and the Iface⋯Cu distances are 0.78 Å (averaged). As a geometric consequence of these properties there are eight distorted trigonal-bipyramidal polyhedra evident, wherein each trigonal face builds up the equatorial site and the opposite Cu⋯I positions form the axial site. As expected, the n-butyl moieties are highly flexible, resulting in large elongations of their anisotropic displacement parameters. Some C atoms of the n-butyl groups were needed to fix alternative discrete disordered positions.

Crystal structures of three complexes of zinc chloride with tri-tert-butyl-phosphane.

Project description:Under anhydrous conditions and in the absence of a Lewis-base solvent, a zinc chloride complex with tri-tert-butyl-phosphane as the μ-bridged dimer is formed, viz. di-μ-chlorido-bis-[chlorido-bis-(tri-tert-butyl-phosphane)zinc], [ZnCl4(C12H27P)2], (1), which features a nearly square-shaped (ZnCl)2 cyclic core and whose Cl atoms inter-act weakly with C-H groups on the phosphane ligand. In the presence of THF, monomeric di-chlorido-(tetra-hydro-furan-κO)(tri-tert-butyl-phosphane-κP)zinc, [ZnCl2(C4H8O)(C12H27P)] or [P(tBu3)(THF)ZnCl2], (2), is formed. This slightly distorted tetra-hedral Zn complex has weak C-H⋯Cl inter-actions between the Cl atoms and phosphane and THF C-H groups. Under ambient conditions, the hydrolysed complex tri-tert-butyl-phospho-nium aqua-tri-chlorido-zincate 1,2-di-chloro-ethane monosolvate, (C12H28P)[ZnCl3(H2O)]·C2H4Cl2 or [HPtBu3](+) [(H2O)ZnCl3](-)·C2H4Cl2, (3), is formed. This complex forms chains of [(H2O)ZnCl3](-) anions from hydrogen-bonding inter-actions between the water H atoms and Cl atoms that propagate along the b axis.

A triclinic polymorph of bis-(?-di-tert-butyl-phosphanido)bis-[(di-tert-butyl-phosphane)palladium(I)].

Project description:A new polymorph of the title compound, [Pd(2)(C(8)H(18)P)(2)(C(8)H(19)P)(2)], has been found. It belongs to the triclinic P-1 space group, whereas the known form [Leoni, Sommovigo, Pasquali, Sabatino & Braga (1992 ?), J. Organo-met. Chem.423, 263-270] crystallizes in the monoclinic C2/c space group. The title compound features a dinuclear palladium complex with a planar central Pd(2)(?-P)(2) core (r.m.s. deviation = 0.003?Å). The Pd-Pd distance of 2.5988?(5)?Å is within the range of a Pd(I)-Pd(I) bond. The mol-ecules of both polymorphs are located on a crystallographic centre of inversion. The mol-ecular conformations of the two polymorphs are essentially identical. The crystal packing patterns, on the other hand, are slightly different.

(Di-tert-butyl-phosphan-yl)bis-(diphenyl-phosphan-yl)phosphane.

Project description:The title phosphane, C(32)H(38)P(4) or (Ph(2)P)(2)P(P(t)Bu(2)), has a P atom that is linked to another three P atoms in a pyramidal configuration; the P-P distances in the range 2.2231 (7)-2.2446 (7) Å indicate that the P-P bonds are single bonds.

Crystal structure of di-?-iodido-bis-[(dimethyl sulfoxide-?O)(tri-phenyl-phosphane-?P)copper(I)].

Project description:The centrosymmetric dinuclear title compound, [Cu2I2(C2H6OS)2(C18H15P)2], represents the first example of a CuI complex ligated by an O-bound dimethyl sulfoxide ligand. In the crystal, the two tetrahedrally coordinated Cu(I) atoms are bridged by two ?2-iodido ligands in an almost symmetrical rhomboid geometry. The loose Cu?Cu contact of 2.9874?(8)?Å is longer than the sum of the van der Waals radii of two Cu atoms (2.8?Å), excluding a significant cupriophilic inter-action in the actual dimer. C-H?O and C-H?I hydrogen bonding interactions as well as C-H??(aryl) interactions stabilize the three-dimensional supramolecular network.

1-Butyl-3-methyl-imidazolium tri-bromido-(tri-phenyl-phosphane-κ<i>P</i>)nickelate(II) butan-1-ol hemisolvate.

Project description:The solvated title salt, (C8H15N2)[NiBr3(P(C6H5)3)]·0.5C4H10O, was obtained in the form of single crystals directly from the reaction mixture. The mol-ecular structure consists of separated 1-butyl-3-methyl-imidazolium cations, tri-bromido-(tri-phenyl-phosphane)nickelate(II) anions and half a solvent mol-ecule of 1-butanol, all connected via multiple hydrogen contacts to form a three-dimensional network. The co-crystallized 1-butanol mol-ecule is disordered and adopts two orientations. The central C-C bonds of both orientations are located on an inversion centre (Wyckoff site 2b of space group P21/n). Thereby, each orientation has again two orientations with the OH group being located either on one or the other side of the C4 alkyl chain. The dried solvent-free compound exhibits a relatively low melting point (m.p. = 412 K).

Project description:The half-sandwich title compound, [Yb(2)(C(13)H(21))(2)I(2)(C(4)H(10)O)(2)], crystallizes as a centrosymmetric dimer. The Yb atom is coordinated in a three-legged piano-stool geometry by a cyclo-penta-dienyl ring, two I anions and the O atom of a diethyl ether mol-ecule. The central Yb(2)I(2) core is an approximate square.

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.
