Tris[?-1,2-bis-(diphenyl-phosphino)-ethane]-1:2?P:P';1:3?P:P';2:3?P:P'-di-?-bromido-1:2?Br:Br-bromido-3?Br-tricopper(I) acetone hemisolvate.

ABSTRACT: In the crystal structure of the title compound, [Cu(3)Br(3)(C(26)H(24)P(2))(3)]·0.5CH(3)COCH(3), two of the Cu centers are bridged by two bromide anions forming a Cu(?-Br)(2)Cu core, which is further bridged by a 1,2-bis-(diphenyl-phosphino)-ethane (dppe) ligand. The third Cu center is terminally bound to another bromide ligand and is connected to the other two Cu atoms by bridging dppe ligands, forming a triangular cluster unit. The acetone solvent mol-ecule exhibits twofold disorder about an inversion centre at (, 1, 0). The crystal structure is stabilized by inter-molecular C-H?Br hydrogen bonds.

μ-1,2-Bis(diethyl-phosphino)ethane-κP:P'-bis-{[1,2-bis-(diethyl-phosphino)ethane-κP,P']trichloridonitrosyl-tungsten(II)}.

Project description:The title binuclear compound, [W(2)Cl(6)(NO)(2)(C(10)H(22)P(2))(3)], contains two W atoms which are bridged by a bis-(diethyl-phosphino)-ethane (depe) ligand. The seven-coord-inated tungsten(II) centres display distorted penta-gonal-bipyramidal geometries with trans nitrosyl and chloride ligands. The title mol-ecule lies on a crystallographic inversion centre. The ethane group of the non-bridging depe ligand is positionally disordered, with site-occupancy factors of 0.63 and 0.37. In the crystal structure, the binuclear mol-ecules are linked by weak inter-molecular C-H⋯O and C-H⋯Cl inter-actions. In addition, weak intra-molecular C-H⋯Cl inter-actions are also present.

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.

μ-Bromido-bis{μ-2,2'-[4,7-diaza-decane-1,10-diylbis(nitrilo-methanylyl-idene)]diphenolato}tricopper(II) bromide dimethyl-formamide disolvate.

Project description:The complex mol-ecule of the title compound, [Cu(3)Br(C(22)H(28)N(4)O(2))(2)]Br·2C(3)H(7)NO, contains three copper atoms, two of which are five-coordinate within a square-pyramidal environment and linked by a bridging Br atom occupying the apical position in each square pyramid. The remaining Cu atom is four-coordinate but with considerable tetra-hedral disortion [the dihedral angle between the two chelate planes is 69.21 (7)°]. There are two mol-ecules of dimethyl-formamide (DMF) present as solvent mol-ecules, one of which is disordered over two equivalent conformations with occupancies of 0.603 (5) and 0.397 (5). The amine H atoms are involved in both inter- and intra-molecular hydrogen-bonding inter-actions with the Br and O atoms of the cation, as well as with the O atom of the ordered DMF mol-ecule.

?-1,2-Bis-(diphenyl-phos-phino)-ethane-?P:P'-bis-{[1,2-bis-(diphenyl-phosphino)-ethane-?P,P']bromidocopper(I)} acetone disolvate.

Project description:In the crystal structure of the title compound, [Cu(2)Br(2)(dppe)(3)]·2CH(3)COCH(3) [dppe is 1,2-bis-(diphenyl-phosphino)-ethane, C(26)H(24)P(2)], the two Cu centers are bridged by a dppe ligand and each metal center carries one chelating dppe unit, with the fourth coordination site available for the Br(-) anion. The mol-ecule is centrosymmetric, with the center of symmetry located between the methyl-ene C atoms of the bridging dppe ligand. The crystal structure is stabilized by intra-molecular C-H?Br hydrogen bonds and inter-molecular ?-? inter-actions, with a centroid-to-centroid distance of 3.2055?(1)?Å.

[μ-Bis(diphenyl-phosphan-yl)ethane-1:2κP:P']nona-carbonyl-1κC,2κC,3κC-(triphenyl-stibine-3κSb)-triangulo-triruthenium(0).

Project description:The asymmetric unit of the title triangulo-triruthenium compound, [Ru(3)(C(26)H(24)P(2))(C(18)H(15)Sb)(CO)(9)], consists of two crystallographically independent mol-ecules, A and B. The bis-(diphenyl-phosphan-yl)ethane ligand bridges an Ru-Ru bond and the monodentate stibine ligand bonds to the third Ru atom. Both the stibine and phosphine ligands are equatorial with respect to the Ru(3) triangle. Additionally, each Ru atom carries one equatorial and two axial terminal carbonyl ligands. The three stibine-substituted benzene rings make dihedral angles of 38.7 (3), 71.5 (3) and 70.0 (3)° with each other in mol-ecule A whereas these angles are 83.9 (3), 88.2 (3) and 56.8 (3)° in mol-ecule B. Similarly, the dihedral angles between the two benzene rings are 80.7 (3) and 87.6 (3)° for the two diphenyl-phosphanyl groups in mol-ecule A and 84.0 (3) and 72.6 (4)° in mol-ecule B. In the crystal, mol-ecules are linked into tetra-mers via inter-molecular C-H⋯O hydrogen bonds. Weak inter-molecular C-H⋯π inter-actions further stabilize the crystal structure.

Bis[μ(2)-bis-(diphenyl-phosphino)methane]bis-(μ(2)-ethane-1,2-dithiol-ato)-μ(4)-sulfido-μ(2)-sulfido-disulfidodimolybdenum(V)disilver(I) dimethyl-formamide tris-olvate.

Project description:Treatment of [Et(4)N](2)[(edt)(2)Mo(2)S(2)(μ-S)(2)] (edt = ethane-dithio-l-ate) with two equivalents of Ag(CH(3)CN)(4)ClO(4) in the presence of bis-(diphenyl-phosphino)methane (dppm) ligand gives rise to the title tetra-nuclear cluster, [Ag(2)Mo(2)(C(2)H(4)S(2))(2)S(4)(C(25)H(22)P(2))(2)]·3C(3)H(7)NO. The complex mol-ecule and one of the dimethyl-formamide (DMF) solvent mol-ecules occupy special positions on a mirror plane. The mol-ecular structure of the complex may be visualized as being built of [Mo(2)S(2)(μ-S)(2)(edt)(2)](2-) dianions and [Ag(2)(dppm)(2)](2+) dications connected by two Ag-μ-S(edt) and two Ag-μ(4)-S bonds.

Tri-phenyl-telluronium(IV) bromide acetone hemisolvate.

Project description:The asymmetric unit of the title compound, 2C18H15Te(+)·2Br(-)·C3H6O or Ph3TeBr·0.5Me2CO, contains two crystallographically independent tri-phenyl-telluronium cations, two bromide anions, and one disordered [site-occupancy ratio = 0.581?(7):0.419?(7)] solvent mol-ecule. Inter-ionic Te?Br inter-actions connect the cations and anions into a tetra-meric step-like structure. The primary coordination spheres of both Te atoms are TeC3 trigonal pyramids: three short secondary tellurium-bromine inter-actions expand the coordination geometry of one of the Te atoms to an octa-hedron. While the other Te atom shows only two Te?Br secondary bonding inter-actions, it is also six-coordinated due to a Te?? inter-action [3.769?(2)?Å] with one of the phenyl rings of the adjacent cation.

Crystal structure of bis-(ethyl-enedi-thio)-tetra-thia-fulvalenium μ2-acetato-bis-[tri-bromido-rhenate(III)] 1,1,2-tri-chloro-ethane hemisolvate.

Project description:The asymmetric unit of the title salt, (C10H8S8)[Re2Br6(CH3COO)]·0.5C2H3Cl3, contains one bis-(ethyl-enedi-thio)-tetra-thia-fulvalene (ET) radical cation, one μ2-acetato-bis-[tri-bromido-rhenate(III)] anion and a 1,1,2-tri-chloro-ethane mol-ecule with half-occupancy disordered about a twofold rotation axis. The tetra-thia-fulvalene fragment adopts an almost planar configuration typical of the ET radical cation. The C atoms of both ethyl-enedi-thio fragments in the cation are disordered over two orientations with occupancy factors 0.65:0.35 and 0.77:0.23. In the anion, six Br atoms and a μ2-acetate ligand form a strongly distorted cubic O2Br6 coordination polyhedron around the Re2 dinuclear centre. In the crystal, centrosymmetrically related ET cations and Re2O2Br6 anions are linked into dimers by π-π stacking inter-actions [centroid-to-centroid distance = 3.826 (8) Å] and by pairs of additional Re⋯Br contacts [3.131 (3) Å], respectively. The dimers are further packed into a three-dimensional network by non-directional inter-ionic electrostatic forces and by C-H⋯Br and C-H⋯S hydrogen bonds. The disordered 1,1,2-tri-chloro-ethane mol-ecules occupy solvent-accessible channels along the b axis.
