[?-1,2-Bis(diphenyl-phosphino)ethane-?P:P']bis-{[1,2-bis-(diphenyl-phosphino)ethane-?P,P']cyanidocopper(I)} methanol disolvate.

Project description:The title centrosymmetric complex, [Cu(2)(CN)(2)(C(26)H(24)P(2))(3)]·2CH(3)OH, consists of two five-membered [Cu(dppe)CN] rings [dppe is 1,2-bis-(diphenyl-phosphino)ethane] bridged by one ?(2)-dppe ligand, and two methanol solvent mol-ecules. The angles around the central metal atom indicate that each Cu(I) atom is located in the center of a distorted tetra-hedron. The coordination sphere of each Cu(I) atom is formed by three P atoms from two dppe ligands, and one C atom from the cyanide ligand. The crystal structure is stabilized by O-H?N hydrogen bonds, which are formed by the O-H donor group from methanol and the N-atom acceptor from a cyanide ligand.

Project description:In the crystal structure of the title compound, [MoF(N(2)H(2))(C(31)H(29)N(2)P(2))(C(26)H(24)P(2))](BF(4))(2), each Mo atom is surrounded by four P atoms of one 1,2-bis-(diphenyl-phosphino)ethane and one 2-[bis-(diphenyl-phosphinometh-yl)amino]pyridinium ligand. The remaining binding sites of the distorted octa-hedron are occupied by a hydrazidate (NNH(2) (2-)) and a fluoride ligand. Two F atoms of an anion are disordered over two positions; the site occupancy factors are ca 0.7 and 0.3.

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.

[1,2-Bis(dimethyl-phosphino)ethane]carbon-yl(η-cyclo-penta-dien-yl)iron(II) diphenyl-phosphinoylborate.

Project description:In the title compound, [Fe(C(5)H(5))(C(6)H(16)P(2))(CO)](C(12)H(13)BOP), the Fe(II) ion adopts a three-legged piano-stool geometry, with Fe⋯Cg = 1.721 (5)Å (Cg = the centroid defined by the C atoms of the cyclo-penta-dienyl ring). The 1,2-bis-(dimethyl-phosphino)ethane (dmpe) ligand chelates to form a five-membered C(2)P(2)Fe ring which is in a pseudo-half-chair conformation. In the crystal structure, associations of one cation and two anions are formed via weak inter-molecular C-H⋯O hydrogen bonds, giving rise to R(4) (2)(9) rings.

1,2-Bis{bis-[4-(trifluoro-meth-yl)phen-yl]phosphino}ethane.

Project description:Crystals of the title compound, C(30)H(20)F(12)P(2) or R(2)PCH(2)CH(2)PR(2) (R = 4-C(6)H(4)CF(3)), were inadvertently prepared while attempting to recrystallize a crude sample of trans-Re(Cl)(N(2))(R(2)PCH(2)CH(2)PR(2))(2) from diethyl ether. The molecule lies on a center of inversion. One of the rings lies approximately in the P-C-C-P plane; the dihedral angle is 174.53°.The other ring is not quite perpendicular; the dihedral angle is 71.1°. The compound is isostructural with the R = Ph, 4-C(6)H(4)CH(3) and 4-C(6)H(4)CH(2)CH(3) analogues. It is well known that the basicity of phosphines and diphosphines can be altered by changing the electron-donating ability of R; however, the structural parameters for the title compound do not significantly differ from those of the aforementioned substituted-phenyl compounds.

Bis(1-{bis-[2-(diphenyl-phosphino-yl)eth-yl]phosphan-yl}-2-(diphenyl-phosphan-yl)ethane)dinitratoplatinum(II) methanol tetra-solvate.

Project description:In the title compound, [Pt(NO(3))(2)(C(42)H(42)O(2)P(4))(2)]·4CH(3)OH, the Pt atom positioned on a crystallographic centre of inversion. The two symmetry-equivalent nitrate anions are weakly coordinated to the Pt(II) ion, creating, together with four P ligand atoms, a distorted octa-hedral coordination environment. In addition, several close C-H⋯O contacts between the nitrate O atoms and phenyl H atoms are found. Hydrogen bonds from two methanol solvent mol-ecules to one of the O-P groups complete the crystal structure.

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.
