The asymmetric unit of the title complex, [NiBr(NO){P(C6H5)3}2], comprises two independent mol-ecules each with a similar configuration. The Ni(II) cation is coordinated by one bromide anion, one nitrosyl anion and two tri-phenyl-phosphane mol-ecules in a distorted BrNP2 tetra-hedral coordination geometry. The coordination of the nitrosyl group is non-linear, the Ni-N-O angles being 150.2 (5) a...

To 80 ml 37% aqueous formaldehyde and 80 ml concentrated HCl solution, di-tertbutyl(chloro)phosphane (8.2 ml, 43.0 mol) was added and the mixture was heated to 100 ̊C and stirred overnight. The solution was allowed to cool, then neutralized with NaOH (14 g) and NaHCO3 (7.0 g), extracted with CHCl3 (200 x 3 ml), washed with brine (100 ml), dried with Na2SO4 and the solvent was removed under reduc...

The crystal structure of the title compound, [Os(C(6)H(7)S)Cl(C(18)H(15)P)(2)(CO)], confirms the formulation as an osmabenzene. There is a slightly distorted octa-hedral coordination environment at the Os(II) ion, with the triphenyl-phosphane ligands mutually trans and the chloride cis to the carbon bearing the -SMe substituent. Within the metallacyclic ring, the C-C distances are appropriate f...

The title compound, [Co2{P(C6H5)2}2(C3H9P)4], was obtained by the addition of di-phenyl-phosphane to a solution of Co(CH3)(C3H9P)4. The dinuclear complex mol-ecule exhibits inversion symmetry with the inversion centre located between the two Co(I) atoms. The short Co-Co distance of 2.3670 (8) Å lies within the range of metal-metal double bonds. As a result of inversion symmetry, the four-member...

The mononuclear mixed-ligand title complex, [CuCl(C7H7N3O2S)(C18H15P)2], displays a distorted tetra-hedral coordination sphere around the CuI atom, with two P atoms from two tri-phenyl-phosphane mol-ecules, one terminal S atom from a 1-(4-nitro-phen-yl)thio-urea mol-ecule and a chloride ion as ligands. An intra-molecular N-H⋯Cl hydrogen bond stabilizes the mol-ecular conformation [graph-set mot...

The title compound, [Co(C(27)H(25)O(2)P(2))I(C(3)H(9)P)], was synthesized by the addition of 1-iodo-butane to a solution of the parent cobalt complex {1,3-bis-[(diphenyl-phosphan-yl)-oxy]prop-2-yl}bis-(trimethyl-phosphane)cobalt(II). Two five-membered cobaltocycles with considerable ring bending (sum of inter-nal angles = 516.4 and 517.7°) are formed through two P atoms of the PPh(2) groups and...

In the title compound, [CuI(C(12)H(9)BrN(2))(C(18)H(15)P)], the Cu(I) ion is bonded to one I atom, one triphenyl-phosphane P atom and two N atoms of the diimine ligand in a distorted tetra-hedral geometry. The Schiff base acts as a chelating ligand and coordinates to the Cu(I) atom via two N atoms. In the diimine ligand, the dihedral angle between the pyridine and bromo-phenyl rings is 19.2 (2)...

1-(N,N-Dimethylaminomethyl)-1'-(diphenylphosphanyl)ferrocene (1) was synthesized in good yield by lithiation of 1-bromo-1'-(diphenylphosphanyl)ferrocene and subsequent reaction with Eschenmoser's salt (dimethylmethylideneammonium iodide). Making use of an easily accessible, nontoxic starting material, this procedure represents a convenient alternative to the original synthetic protocol based on...
