Dihydro-nium hexa-kis[bromido/chlorido(0.75/0.25)]dicadmate(II)-triphenyl-phosphine oxide (1/6).

ABSTRACT: In the salt, (H(3)O)(2)[Cd(2)Br(4.5)Cl(1.5)]·6C(18)H(15)OP, the hydro-nium cation forms short O-H?O hydrogen bonds to the O atoms of the triphenyl-phosphine oxide units. The centrosymmetric dinuclear anion has two halide atoms functioning in a bridging mode, which confers tetra-hedral coordination to the Cd atom. The three independent halide atoms are each a mixture of bromide and chloride; the occupancies of the Br atoms are 0.6434?(11), 0.7468?(11) and 0.8598?(11).

The Cu-As bond of the independent arsine ligand is shorter than the Cu-As bonds of the three symmetry-related arsine ligands.

trans-Chlorido[6-chloro-4-(4-methoxy-benz-yl)-3-oxo-3,4-dihydro-pyrazin-2-yl]-bis-(triphenyl-phosphine)palladium(II).

Project description:The title compound, [Pd(C(12)H(10)ClN(2)O(2))Cl(C(18)H(15)P)(2)], is the inter-mediate of the reduction of a 3,5-dichloro-pyrazinone [Loosen, Tutonda, Khorasani, Compernolle & Hoornaert (1991 ?). Tetra-hedron, 47, 9259-9268]. This species is formed by oxidative addition of coordinatively unsaturated Pd(0) to the reactive 3-position of the heterocycle. The coordination around the Pd atom is square planar, with two trans PPh(3) ligands. ?-? inter-actions are observed between the centroid of the pyrazinone ring and planes of two adjacent phenyl rings, one from each PPh(3) group (3.25 and 3.078?Å), stabilizing the inter-mediate structure. This could explain the reduced reactivity towards substitution of the Cl atom by the formate anion, resulting in poor yield of the reduced compound. 3-Substituted pyrazinones are important precursors in the synthesis of 5-amino-piperidinone-2-carboxyl-ate (APC) systems.

Bis(?(2)-phenyl-tellurolato)bis-(phenyl-tellurolato)tetra-?(3)-tellurido-hexa-kis(triphenyl-phosphine)hexa-palladium(II) benzene nona-solvate.

Project description:The centrosymmetric title complex, [Pd(6)(C(6)H(5)Te)(4)Te(4)(C(18)H(15)P)(6)]·9C(6)H(6), contains two Pd(3)Te(2) cores that are joined into a cyclic hexa-nuclear complex by two bridging PhTe(-) groups. Each Pd(II) atom is coordinated by one triphenyl-phosphine ligand, one phenyl-tellurolate mol-ecule and two telluride ligands: two of the PhTe(-) ligands act as terminal ligands and two as bridging ligands. The three distinct Pd(II) atoms each show a slightly distorted PdPTe(3) square-planar coordination. The asymmetric unit also contains four and a half benzene solvent mol-ecules. Two of the benzene mol-ecules are disordered: one mol-ecule is distributed over two positions with site-occupancy factors of 0.529?(7) and 0.471?(7), while the other occupies two orientations about a centre of symmetry.

The phenyl ring of one of the six benzyl units was refined as equally disordered over two sets of sites.

Penta-kis(2-oxo-2,3-dihydro-pyrimidin-1-ium) di-?(3)-chlorido-tri-?(2)-chlorido-hexa-chloridotricadmate(II).

Project description:The title compound, (C(4)H(5)N(2)O)(5)[Cd(3)Cl(11)], was obtained from the reaction of 2-hydroxy-pyrimidine hydro-chloride and cadmium(II) chloride in concentrated HCl solution. The crystal structure consists of planar 2-oxo-1,2-dihydro-pyrimidin-3-ium cations with both N atoms protonated and the O atom unprotonated, and a complex trinuclear [Cd(3)Cl(11)](5-) anion of approximately D(3h) symmetry, which has a triangle of three octa-hedrally coordinated Cd(II) centres bonded to 11 chloride ions. Three of the chloride ions bridge adjacent Cd atoms, two cap the faces of the Cd(3) triangle and the remaining six are terminally bonded and act as hydrogen-bond acceptors. Various N-H?Cl hydrogen bonds connect the anions and cations and, in addition, inter-molecular N-H?O hydrogen bonds contribute to the formation of a three-dimensional network.

Di-μ-bromido-tris-(triphenyl-phosphine)-1κP,2κP-disilver(I) tetra-hydro-furan 0.85-solvate.

Project description:In the title binuclear silver(I) complex, [Ag(2)Br(2)(C(18)H(15)P)(3)]·0.85C(4)H(8)O, the two independent silver(I) ions are briged by two bromide ions. One Ag(I) ion is coordinated by two triphenyl-phosphine groups with a square-planar geometry, while the second is coordinated by one triphenyl-phine group with a trigonal-planar geometry. The structure is very similar to that of the dichloro-methane solvate reported by Zhu, Huang & Zheng [Chin. J. Struct. Chem. (1994), 13, 325-327]. The tetrahydrofuran solvent molecule is disordered and was refined with a fixed occupancy of 0.85.
