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 title compound, [Fe(2)(C(3)H(6)S(2))(C(18)H(15)P)(2)(CO)(4)], which might serve as an active-site model of [FeFe]-hydrogenase, contains two fused Fe/S/C/C/C/S six-membered rings, one of which has a chair conformation and the other a boat conformation. Each Fe atom is coordinated by two carbonyl ligands, a triphenyl-phosphane ligand and a bis-bidentate dithiol-ate ligand, and also forms an F...

The tripodal, tetradentate tris(1-(diphenylphosphanyl)-3-methyl-1H-indol-2-yl)phosphane PP3 -ligand 1 stabilizes Ru in the RuII , RuI , and Ru0 oxidation states. The octahedral [(PP3 )RuII (Cl)2 ] (2), distorted trigonal bipyramidal [(PP3 )RuI (Cl)] (3), and trigonal bipyramidal [(PP3 )Ru0 (N2 )] (4) complexes were isolated and characterized by single-crystal X-ray diffraction, NMR, EPR, IR, an...

The title compound, [Pd2{P(C10H7)2(C10H6)}2Cl2]·2CH2Cl2, shows cyclo-metalation of one naphthalen-1-yl substituent of each of the phosphane ligands to the Pd dimer in a trans orientation; the complete dimer is generated by a centre of inversion. Two dichloro-methane solvent mol-ecules create C-H⋯Cl inter-actions with the metal complex, generating supermolecular layers in the ab plane. Additiona...

In the title complex, [Cu(NO(3))(C(18)H(12)F(3)P)(3)], the ligating atoms define a distorted tetrahedon with the three tris-(4-fluoro-phen-yl)phosphane ligands in the basal positions and the nitrate ligand in the axial position. The intra-molecular π-π inter-action [centroid-centroid distance = 3.6113 (11) Å] between two of the 4-fluoro-phenyl groups is complemented by both C-H⋯F and C-H⋯O inte...

The title compound, [Co(C(5)H(5))(C(18)H(15)P)(2)]·0.2C(7)H(8)·0.25C(6)H(14), was synthesized by the reaction of cobaltocene, Cp(2)Co, with elemental lithium in tetra-hydro-furan in the presence of two equivalents of PPh(3). The mol-ecular structure displays a cobalt(I) center in a distorted trigonal-planar coordination environment, with one Cp and two phosphane ligands. There are two crystallo...

The title compound, [Fe(NO)(2)(C(18)H(12)F(3)P)(2)]·CHCl(3), belongs to the family of metal dinitrosyl compounds with the general formula Fe(NO)(2)(L)(x), referred to collectively as 'dinitrosyl iron compounds' (DNICs). Herein we report the structure of a dinitrosyl iron diphosphane complex, (Fe(NO)(2)L(2), with L = P(C(6)H(4)-p-F)(3). The structure includes one metal complex mol-ecule and one ...

The title structure,[IrCl(C(8)H(12))(C(14)H(10)F(5)P)], reveals that (C(2)F(5))PPh(2) (penta-fluoro-ethyl-diphenyl-phosphane or pfepp) disrupts the iridium dimer [(cod)IrCl](2) (cod = cyclo-octa-1,5-diene) by rupturing the bridging chloride ligands and binding in the open coordination site to form (cod)Ir(pfepp)Cl with the Ir(I) atom in a distorted square-planar coordination environment. The st...

In the title salt, [Ag(CH4N2S)2(PPh3)2]NO3, the Ag(I) atom is coordinated by two thio-urea S atoms and two tri-phenyl-phosphane P atoms in a distorted tetra-hedral geometry, with bond angles in the range 102.90 (4)-123.29 (4)°. The Ag-S=C bond angles are 101.75 (19) and 111.29 (18)°. In the crystal, the component ions are linked by C-H⋯O, C-H⋯S, N-H⋯O and N-H⋯S hydrogen bonds, generating (10-1)...

In the title compound, trans-[RhCl(C(20)H(17)P)(2)(CO)], the Rh(I) atom is situated on a center of symmetry, resulting in a statistical 1:1 disorder of the chloride [Rh-Cl = 2.383 (2) Å] and carbonyl [Rh-C = 1.752 (7) Å] ligands. The distorted trans square-planar environment is completed by two P atoms [Rh-P = 2.3251 (4) Å] from two diphen-yl(4-vinyl-phen-yl)phosphane ligands. The vinyl group i...
