Colourless needle-shaped crystals of the title compound, (C(26)H(21)BrOP)(2)[Hg(2)Br(6)], have been prepared by addition of a solution of HgBr(2) in methanol to a solution of (4-bromo-benzoyl-meth-yl)triphenyl-phospho-rane in dry methanol. The compound features Hg(2)Br(6) (2-) dianions, whose site symmetry is .

The title compound, [Sb(2)(C(6)H(5))(6)(CH(3)O)(2)O]·2CH(3)OH, is the methanol disolvate of a dinuclear triphenyl-anti-mony derivative. The mol-ecule shows C(s) symmetry. The Sb-O-Sb angles cover a range from 89.65 (10)° to 102.08 (13)°. In the crystal structure, two O-H⋯O hydrogen bonds are present.

Monodisperse, size-controlled Ni-P nanoparticles were synthesised in a single step process using triphenyl-phosphane (TPP), oleylamine (OA), and Ni(II)acetyl-acetonate. The nanoparticles were amorphous, contained ~30 at% P and their size was controlled between 7-21 nm simply by varying the amount of TPP. They are catalytically active for tailored carbon nanotube growth.

The title compound, [Ni(C(14)H(9))Cl(C(18)H(15)P)(2)], was synthesized from the reaction between 9-chloro-phenanthrene, NiCl(2)·6H(2)O and triphenyl-phosphane in ethanol. The bond angles around the Ni(II) atom indicate that it exists in a slightly distorted square-planar geometry.

The synthesis and characterization of a novel class of highly-metallized, redox-active polyelectrolytes that employ phosphorus as a scaffold for the installation of transition metals is described. Pyrolysis of thin films of the title polyelectrolytes resulted in the production of magnetite crystallites and ill-defined carbon-, phosphorus- and oxygen-rich phases in char yields of nearly 50%.

The first examples of arylphosphonium salts containing a dicarba-closo-dodecaborane(12) (closo-carborane) are reported; in contrast to the 1,12-carborane derivative, the 1,2- and 1,7-isomers undergo a facile deboronation reaction in polar solvents to afford the corresponding nido-carborane phosphonium zwitterions.

In the crystal structure of the title compound, [Ru(C(4)H(6)BN(6))H(C(18)H(15)P)(2)(CO)]·C(2)H(3)N, discrete mononuclear complexes are found in which the Ru atom is coordinated by two triphenyl-phosphine (PPh(3)) ligands, one dihydro-bis(1,2,4-triazol-1-yl)borate ligand, one carbonyl ligand and one hydride atom within slightly distorted octa-hedra. The two P atoms of the PPh(3) ligands are tran...

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...
