[?-Bis(diphenyl-phosphan-yl)acetonitrile-?P:P]bis-[chloridogold(I)].

ABSTRACT: The title complex, [Au(2)Cl(2)(C(26)H(21)NP(2))], has an intra-molecular Au?Au inter-action of 3.1669?(4)?Å, but no inter-molecular Au?Au inter-actions in the solid state. The Cl-Au-P bond angle of 176.84?(7)° is slightly distorted from linearity. The P-C bond length to the phenyl group is shorter [1.810?(7)?Å] than the P-C bond length [1.876?(7)?Å] to the bridging carbon, indicative of the flexibility of the bidentate bite of the ligand. The C-C N fragment is essentially linear at 179.5?(9)° and the C N bond length of 1.125?(11)?Å indicates predominantly triple-bond character. In the crystal packing, there are no hydrogen-bonding or aurophilic inter-actions between the mol-ecules.

[?-1,2-Bis(diphenyl-phosphan-yl)benzene-?P:P']bis-[chloridogold(I)].

Project description:In the crystal structure of the non-solvate form of the title compound, [Au(2)Cl(2)(C(30)H(24)P(2))], two almost linear P-Au(I)-Cl units [175.87?(3) and 171.48?(3)°] are in a skewed arrangement with a Cl-Au?Au-Cl torsion angle of -65.29?(3)° so as to form an intra-molecular Au?Au inter-action [3.0563?(2)?Å]. The complex mol-ecules are connected each other through inter-molecular C-H?? inter-actions, giving a sheet structure parallel to the bc plane.

Bis[?-bis-(diphenyl-phosphan-yl)methane-?(2) P:P'](?-1-ethyl-thio-urea-?(2) S:S)bis-[iodidocopper(I)] acetonitrile sesquisolvate.

Project description:In the dinuclear title compound, [Cu2I2(C3H8N2S)(C25H22P2)2]·1.5CH3CN, each Cu(I) atom exhibits a distorted tetra-hedral coordination with two P atoms from two bis-(diphenyl-phosphan-yl)methane (dppm) ligands, one metal-bridging S atom from the 1-ethyl-thio-urea (ettu) ligand and one iodide ion. The dppm ligand and the bridging S atom of the ettu ligand force the two copper atoms into close proximity, leading to the formation of a close intra-molecular Cu?Cu contact [3.3747?(17)?Å]. The conformation of the dimeric complex is such that the two dppm ligands are located on one side of the dinuclear metal complex, while the two iodine atoms are pointed towards the other side of the complex, a conformation that is stabilized by two intra-molecular N-H?I hydrogen bonds between the ettu NH2 and NHEt moieties and the I atoms. Another pair of symmetry-equivalent N-H?I hydrogen bonds is established between neighboring mol-ecules across an inversion center, linking mol-ecules into dimers. The dimers are connected with each other and with the inter-stitial acetonitrile solvent mol-ecules via a range of weaker C-H?I and C-H?S inter-actions and through weak C-H?? inter-actions, leading to the formation of a three-dimensional network. One of the acetonitrile solvent mol-ecules is disordered in a 1:1 ratio across a crystallographic inversion center.

Tris(acetonitrile-?N){2,6-bis-[(diphenyl-phosphan-yl)amino]-4-eth-oxy-1,3,5-triazine-?P,N,P'}iron(II) bis-(tetra-fluorido-borate) acetonitrile disolvate.

Project description:In the title compound, [Fe(CH(3)CN)(3)(C(29)H(27)N(5)OP(2))](BF(4))(2)·2CH(3)CN, the Fe(II) ion is octa-hedrally coordinated by a meridionally chelating tridentate pincer-type PNP ligand derived from 2,6-diamino-4-eth-oxy-1,3,5-triazine and by three acetonitrile mol-ecules. The four Fe-N bond lengths range from 1.9142?(12) to 1.9579?(11)?Å, while the Fe-P bonds are 2.2452?(4) and 2.2506?(4)?Å [P-Fe-P = 165.523?(14)°], consistent with Fe(II) in a low-spin state. Unlike related Fe PNP complexes based on 2,6-diamino-pyridine, the BF(4) anions are not hydrogen bonded to the two NH groups of the pincer ligand but show instead anion-? inter-actions with the triazine ring and acetonitrile mol-ecules in addition to ten C-H?F inter-actions. Most remarkable among these is an anion-?(triazine) inter-action with a short distance of 2.788?(2)?Å between one F and the centroid of the ?-acidic triazine ring. The corresponding shortest distance between this F atom and a triazine carbon atom is 2.750?(2)?Å. The two NH groups of the pincer ligand donate N-H?N hydrogen bonds to the triazine N atom of a neighbouring complex and to an uncoordinated acetonitrile mol-ecule. This last mol-ecule is in a side-on head-to-tail association with the second uncoordinated acetonitrile at C?N distances of 3.467?(2) and 3.569?(2)?Å. In contrast to several related compounds with diamino-pyridine- instead of diamino-triazine-based PNP ligands, the title crystal structure is remarkably well ordered. This suggests that the diamino-triazine moiety exerts notable crystal structure stabilizing effects.

N,N-Bis(diphenyl-phosphan-yl)benzyl-amine.

Project description:In the title compound, C(31)H(27)NP(2), the diphenyl-phosphanyl groups are staggered relative to the PNP backbone. The N atom is displaced by 0.219 (2) Å from the plane formed by the two P atoms and the methylene C atom. The angles around the N atom are 120.84 (16), 113.29 (16) and 120.57 (12)°, indicating that it exhibits a distorted trigonal-pyramidal geometry. There are no classical inter-molecular inter-actions.

Project description:In the cation of the title compound, [Ag(4)(C(2)F(3)O(2))(2)(C(12)H(10)O(2)P)(2)(C(25)H(22)P(2))(2)]·2CH(3)CN, the two independent Ag(+) cations are four-coordinated in a distorted tetra-hedral geometry by one P atom from a bis-(diphenyl-phosphan-yl)methane (dppm) ligand, one O atom from a trifluoro-acetate anion and two O atoms from two diphenyl-phosphinate (dpp) ligands. Two dppm ligands, two dpp ligands and two trifluoro-acetate anions bridge four metal atoms, forming a centrosymmetric tetra-nuclear complex. Intra-molecular C-H?O hydrogen bonds and a weak ?-? inter-action [centroid-centroid distance = 3.9804?(13)?Å] are also observed.

trans-Bis[1,2-bis-(diphenyl-phosphan-yl)ethane]-chlorido(ethyn-yl)ruthenium(II).

Project description:The mol-ecular structure of the title compound, trans-[Cu(C2H)Cl(C26H24P2)2], consists of an Ru(II) cation, located on an inversion centre, in an octa-hedral environment defined by two chelating phosphines, one acetyl-ide and one chloride ligand. The -C CH and the chlorine ligands are disordered over two equivalent positions (0.5 occupancy each). The coordination geometry is distorted octa-hedral, with the -C CH fragment and the Cl ligand in trans positions. The four P atoms occupy the equatorial plane of the octa-hedron and the chloride and acetyl-ide ligands the axial positions.

N,N-Bis(diphenyl-phosphan-yl)cyclo--penta-namine.

Project description:The coordination around the N atom in the title compound, C(29)H(29)NP(2), shows an almost planar geometry, defined by the attached P and C atoms, in order to accomodate the steric bulk of the phenyl rings. The distortion of the trigonal-pyramidal geometry of the N atom is illustrated by the bond angles ranging between 115.22?(12) and 121.76?(9)°. The P atoms present a pyramidal environment with bond angles ranging from 100.62?(9) to 104.71?(8)°. One of the C atoms in the cyclo-pentyl ring displays a 0.822?(4):0.178?(4) positional disorder. Within the crystal structure, intra-molecular C-H?P hydrogen bonds together with inter- and intra-molecular C-H?? inter-actions link the mol-ecules into a supra-molecular two-dimensional network.

4,6-Bis(diphenyl-phosphan-yl)dibenzo[b,d]furan.

Project description:The asymmetric unit of the title compound, C(36)H(26)OP(2), comprises two mol-ecules which have slightly different conformations of the phenyl ring substituents. In both mol-ecules, the dibenzofuran unit is close to being planar, with dihedral angles of 3.20 (3) and 1.86 (2)° for the two mol-ecules. Its planarity affects the intra-molecular distances between P atoms, with P⋯P distances of 5.574 (2) and 5.485 (2) Å for the two mol-ecules.
