Bis[?-bis-(diphenyl-phosphino)methane-?P:P']bis-[(2,2'-bipyridine-?N,N')copper(I)] bis-(tetra-fluoro-borate).

ABSTRACT: The centrosymmetric title compound, [Cu(2)(C(10)H(8)N(2))(2)(C(25)H(22)P(2))(2)](BF(4))(2), consists of discrete dinuclear cations and tetra-fluoro-borate anions. The two Cu(I) centers are bridged by the phosphine ligands to form an eight-membered ring. The Cu(I) center exhibits a tetra-hedral coordination as it is chelated by the N-heterocycle.

Tetra-aqua-(2,2'-bipyridine-?N,N')magnesium(II) bis-(4-fluoro-benzoate).

Project description:The title compound, [Mg(C(10)H(8)N(2))(H(2)O)(4)](C(7)H(4)FO(2))(2), consists of a bivalent [Mg(C(10)H(8)N(2))(H(2)O)(4)](2+) cation and two 4-fluorbenzoate anions. In the complex cation, the Mg(II) atom is coordinated by two N atoms from a 2,2'-bipyridine ligand and four water O atoms in a distorted MgN(2)O(4) octa-hedral geometry. The Mg(II) atom is located on a twofold rotation axis and thus a cation exhibits C(2) mol-ecular symmetry. The 2,2'-bipyridine ligands exhibit nearly perfect planarity (r.m.s. deviations = 0.0061?Å). In the crystal, O-H?O and C-H?O hydrogen bonds link the cations and anions into a three-dimensional supra-molecular network.

(2,2'-Bipyridine-?(2) N,N')[bis-(diphenyl-thio-phosphino-yl)meth-yl]lithium(I) benzene monosolvate.

cis-Bis(2,2'-bipyridine-?N,N')bis-(dimethyl sulfoxide-?O)zinc bis-(tetra-phenyl-borate) dimethyl sulfoxide monosolvate.

Project description:In the mononuclear title complex, [Zn(C(10)H(8)N(2))(2)(C(2)H(6)OS)(2)](C(24)H(20)B)(2)·C(2)H(6)OS, the Zn(II) ion is coordinated by four N atoms of two bidentate 2,2'-bipyridine mol-ecules and by the O atoms of two cis-disposed dimethyl sulfoxide mol-ecules in a distorted octa-hedral geometry. The S atom and the methyl groups of one of the coordinated dimethyl sulfoxide mol-ecules are disordered in a 0.509?(2):0.491?(2) ratio. The crystal packing is stabilized by C-H?O hydrogen bonds between the dimethyl sulfoxide solvent mol-ecules and tetra-phenyl-borate anions.

[Bis-(diphenyl-phosphino)methane-?P,P']dichloridopalladium(II).

Project description:The title complex, [PdCl(2)(C(25)H(22)P(2))], is a slightly distorted square-planar bis-(diphenyl-phosphino)methane cis-complex of PdCl(2). The structure of a polymorph of the title compound has been described earlier, but the arrangement of the mol-ecules observed in the current structure is distinctively different from that previously reported [Steffen & Palenik (1976 ?). Inorg. Chem.15, 2432-2439]. The earlier report describes a structure with individual well separated mol-ecules crystallizing in space group P2(1)/n. The polymorph described here, which is isostructrural to its Pt analogue [Babai et al. (2006 ?). Z. Anorg. Allg. Chem.632, 639-644], crystallizes in C2/c with chains of C2-symmetric mol-ecules stretching parallel to the b axis. The Pd atoms and the bis-phosphino-methane units are located on two different positions created by a non-crystallographic mirror operation with an occupancy of 0.6677?(11) for the major (PCH(2)P)Pd moiety. The positions of the Cl atoms of the minor moiety do coincide perfectly with those of the next mol-ecule along the chain parallel to b, and they are thus not included in the disorder. The phenyl rings also do not take part in the disorder and are common to both the major and minor moieties of the (PCH(2)P)PdCl(2) units. Assuming no defects, mol-ecules in each chain will thus have to be oriented the same way and the effect of the disorder of the (PCH(2)P)Pd unit is thus a reversal in direction of the chains parallel to b. The presence of light streaks of intensity between actual Bragg peaks indicates that a somehow ordered arrangement not resolved in the Bragg diffraction data may be present (i.e. an incommensurate superstructure) rather than a random or domain arrangement of the chains.

A tetra-silver(I)ditungsten(VI) cluster with sulfide and bis-(diphenyl-phosphino)methane ligands.

Project description:The asymmetric unit of the title complex, [Ag(4)W(2)S(8)(C(25)H(22)P(2))(3)]·2C(3)H(7)NO, tris-[μ(2)-bis-(diphenyl-phosphino)meth-ane]-3:6κ(2)P:P';4:5κ(2)P:P';5:6κ(2)P:P'-μ(5)-sulfido-2:3:4:5:6κ(5)S-μ(3)-sulfido-1:3:4κ(3)S-tetra-μ(2)-sulfido-1:3κ(2)S;1:4κ(2)S;2:5κ(2)S;2:6κ(2)S-disulfido-1κS,2κS-tetra-silver(I)ditungsten(VI) N,N-dimethyl-formamide disolvate, contains two [WS(4)](2-) anions, four silver cations, three bidentate-bridging bis-(diphenyl-phosphino)methane (dppm) ligands and two N,N-dimethyl-formamide (DMF) solvent mol-ecules. The coordination geometry of each Ag atom is distorted tetra-hedral. Two Ag ions are coordinated by μ(2)-S and μ(5)-S atoms, and by two P atoms from two dppm ligands, while the other two Ag atoms are coordinated by μ(2)-S, μ(3)-S and μ(5)-S atoms, and by one P atom from a dppm ligand.

Bis(2,2'-bipyrimidine-κ(2)N(1),N(1'))palladium(II) bis-(tetra-fluoro-borate) acetonitrile monosolvate.

Project description:The reaction of [Pd(MeCN)(4)](BF(4))(2) with 2,2'-bipyrimidine (bpm) in MeCN-CHCl(3) afforded the title compound, [Pd(C(8)H(6)N(4))(2)](BF(4))(2)·C(2)H(3)N. The asymmetric unit contains two half complexes, with the Pd(II) atoms both lying on a twofold axis. Each metal atom adopts a tetra-hedrally distorted square-planar geometry. In the crystal, [Pd(bpm)(2)] dications are linked by C-H⋯N hydrogen bonds, forming chains parallel to the b axis. The chains are further linked by C-H⋯F and C-H⋯N inter-actions involving the tetra-fluoro-borate anions and acetonitrile mol-ecules. In this way, each chain interacts with six surrounding chains to generate the observed three-dimensional structure.
