Bis[?-1,2-bis-(diphenyl-phosphino)methane-?P:P']bis-[(?-ethene)nickel(0)] toluene disolvate.

ABSTRACT: In the title compound, [Ni(2)(C(2)H(4))(2)(C(25)H(22)P(2))(2)]·2C(7)H(8), each Ni atom is coordinated in a trigonal-planar geometry by two P atoms of the bridging 1,2-bis-(diphenyl-phosphino)methane (dppm) ligands and by the centroid of the double bond of an ethene ligand. An eight-membered ring comprising the two Ni atoms, four P atoms and the CH(2) groups of the two dppm ligands is thus formed. The methyl group in one of the solvent toluene mol-ecules is disordered over two positions with equal occupancies.

[μ-1,3-Bis(diphenyl-phosphino)propane-κP:P']bis-[bromidogold(I)].

Project description:The title compound, [Au(2)Br(2)(C(27)H(26)P(2))], features linearly coordinated Au(I) atoms within P,Br-donor sets. The central portion of the mol-ecule is practically planar as quanti-fied by the Br-Au⋯Au-Br torsion angle of -169.9 (2)°. The P-Au-Br chromophores are twisted with respect to each other [dihedral angle = 52.3 (6)°]. The benzene rings on each P atom lie on either side of this plane. The Au atoms are positioned at the periphery of the mol-ecule, which facilitates the formation of Au⋯Au inter-actions [3.2575 (11) Å] that result in the formation of supra-molecular chains along the b-axis direction. The Au⋯Au inter-actions are responsible for the deviations from the ideal linear geometry for each Au atom.

catena-Poly[[(nitrato-κO,O')silver(I)]-μ-1,2-bis-(diphenyl-phosphino)ethane-κP:P'].

Project description:In the title chain compound, [Ag(NO(3))(C(26)H(24)P(2))](n), the bis-(diphenyl-phosphino)ethane (dppe) units link the Ag(+) ions into chains along [001]. A nitrate anion is coordinated to the Ag atom. There is a centre of symmetry at the mid-point of the ethane C-C bond and a twofold rotation axis passes through the Ag, N and terminal O atoms. Each Ag atom is four-coordinated in a distorted tetra-hedral geometry by two O atoms of the nitrate anion and two P atoms of dppe ligands. The two aromatic rings are oriented at a dihedral angle of 73.77 (3)°.

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.

Bis[cis-bis-(diphenyl-phosphino)ethene]copper(I) dichloridocuprate(I).

Project description:The crystal structure of the title compound, [Cu(C(26)H(22)P(2))(2)][CuCl(2)], is composed of discrete Cu(dppey)(2)](+) cations [dppey is cis-bis-(diphenyl-phosphino)ethene] and [CuCl(2)](-) anions. The tetra-hedral Cu(P-P)(2) core of the [Cu(dppey)(2)](+) cation is distorted, with Cu-P bond lengths ranging from 2.269?(1) to 2.366?(1)?Å. The five-membered -Cu-P-CH=CH-P- rings adopt envelope conformations, with the Cu atom lying 0.38 and 0.65?Å out of the P-C=C-P planes. The Cu-Cl distances in the [CuCl(2)](-) anion are 2.094?(2) and 2.096?(2)?Å, with a Cl-Cu-Cl angle of 176.81?(7)°.

[?-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.

?-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(2)-Bis(diphenyl-phosphanyl)methane][μ(3)-bis-(diphenyl-phosphanyl)meth-yl]trichlorido-tetra-gold(I) tetra-hydro-furan disolvate.

Project description:The title tetra-nuclear complex, [Au(4)(C(25)H(21)P(2))Cl(3)(C(25)H(22)P(2))]·2C(4)H(8)O, features two non-equivalent Ph(2)PCPPh(2) fragments, one of which represents the 'complete' mol-ecule (with two H atoms at the central C atom); each of the two P atoms of this mol-ecule is coordinated by an Au atom [Au-P = 2.2256 (13) and 2.2710 (13) Å], and these two Au atoms form an Au-Au bond [3.2945 (3) Å], thus closing the five-membered Au(2)P(2)C ring. The first of these Au atoms has a terminal chlorido ligand [Au-Cl = 2.2806 (12) Å], whereas the second Au atom forms a covalent bond with the central C atom of the bis-(diphenyl-phosphino)methyl group [Au-C = 2.114 (5) Å]; the latter group in turn coordinates with its P atoms the gold atoms of the Cl-Au-Au-Cl group [Au-P = 2.2356 (13) and 2.2338 (13), Au-Au = 3.3177 (3), Au-Cl = 2.3091 (12) and 2.2950 (13) Å], thus closing the second Au(2)P(2)C ring. The two such rings have different chemical functions, but both exhibit envelope conformations. However, the first (with different substituents at the Au atoms) is non-symmetrical with one of the P atoms in the flap position of the envelope; the other one has a conformation with mirror symmetry, and the gold-substituted C atom is displaced by 0.740 (5) Å from the almost exactly planar (r.m.s. deviation = 0.0038 Å) Au(2)P(2) group.

[Bis(diphenyl-phosphino)methane-?P,P'][bis-(diphenyl-phosphinometh-yl)diethoxy-silane-?P,P']bis-(dinitro-gen)-molybdenum(0) benzene 0.7-solvate.

Project description:In the crystal structure of the title compound, [Mo(C(25)H(22)P(2))(C(30)H(34)O(2)P(2)Si)(N(2))(2)]·0.7C(6)H(6), the Mo atoms are coordinated by four P atoms and two N atoms in a distorted octa-hedral mode. The two C atoms of one of the two eth-oxy groups are disordered and were refined using a split model and site-occupation factors of 0.7:0.3. The crystal structure contains a benzene solvent mol-ecule with a site occupation of 70%.
