Bis{1-[2-(diphenyl-phosphan-yl)eth-yl]-3-ethyl-imidazol-2-yl-idene}nickel(II) diiodide acetonitrile disolvate.

ABSTRACT: The mol-ecular structure of the title compound, [Ni(C(19)H(21)N(2)P)(2)]I(2)·2CH(3)CN, shows two six-membered N-heterocyclic carbene/phosphane chelate rings that form a nearly square-planar coordination geometry around the Ni(II) atom, which lies 0.190?(1)?Å above the C(2)P(2) plane. The sum of the bond angles at the Ni(II) atom is 358.68?(6)°, with C-Ni-P bite angles of 82.89?(5) and 84.08?(6)°. The two carbene rings make a dihedral angle of 52.65?(8)°.

The mol-ecular structure of the title compound, [Ni(C(19)H(21)N(2)P)(2)]I(2)·2CH(3)CN, shows two six-membered N-heterocyclic carbene/phosphane chelate rings that form a nearly square-planar coordination geometry around the Ni(II) atom, which lies 0.190 (1) Å above the C(2)P(2) plane. The sum of the bond angles at the Ni(II) atom is 358.68 (6)°, with C-Ni-P bite angles of 82.89 (5) and 84.08 (6)°. The two carbene rings make a dihedral angle of 52.65 (8)°. ...[more]

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.

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

Project description: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.

Project description:In the title complex, [Pd(C(34)H(33)NP(2))(C(17)H(14)O)], the Pd(0) atom is coordinated in a trigonal planar geometry formed by two P atoms of a bis-[(diphenyl-phosphino)eth-yl]aniline ligand and a C=C (?(2)) bond involving the C atoms that are in the ?,? positions relative to the central ketone of the dibenzyl-ideneacetone ligand.

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.

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.

Acetonitrile-trichloridobis(cyclo-hexyl-diphenyl-phosphane)rhodium(III) acetonitrile disolvate.

Project description:In the title compound, [RhCl(3)(CH(3)CN)(C(18)H(21)P)(2)]·2CH(3)CN, the complex mol-ecule lies on a twofold rotation axis that passes through the Rh(III) atom, one Cl atom, and the C and N atoms of the coordinated acetonitrile mol-ecule. The Rh(III) atom is coordinated by two P atoms in trans positions, three Cl atoms and an acetonitrile mol-ecule in a distorted octa-hedral geometry. Intra-molecular C-H?Cl inter-actions are observed. The uncoordinated acetonitrile mol-ecule is disordered over two sites with occupancies of 0.588?(4) and 0.412?(4).

[2-(1-{2-[Aza-nid-yl(ethyl-sulfan-yl)methyl-idene-?N]hydrazin-1-yl-idene-?N¹}eth-yl)phenolato-?O](pyridine-?N)nickel(II).

Project description:The Ni(II) atom in the title complex, [Ni(C??H??N?OS)(C?H?N)], exists within a square-planar N?O donor set provided by N,N',O atoms of the dianionic tridentate ligand and a pyridine N atom. The maximum deviation from the ideal geometry is seen in the N-Ni-N five-membered chelate bite angle of 83.28?(12)°. The pyridine mol-ecule forms a dihedral angle of 44.43?(6)° with the N?O donor set. Supra-molecular stacks along the a axis mediated by alternating ?-? inter-actions between the pyridine and five- [centroid-centroid distance = 3.4784?(16)?Å] and six-membered [3.4633?(17)?Å] chelate rings, feature in the crystal packing.
