In the title compund, C(21)H(33)PSe, the Se=P bond is part of a distorted tetra-hedral environment on the P atom. Both cyclo-hexyl groups adopt chair conformations. A cone angle of 170° was calculated using an adaptation of the Tolman model. Inter-molecular C-H⋯Se and C-H⋯Cg contacts are observed (Cg is the centroid of the benzene ring).

The title compound, [Fe(C(7)H(5)FN)Cl(C(3)H(9)P)(3)], was obtained as a product of the reaction of [Fe(Me(3)P)(4)] with a molar equivalent of (2-chloro-6-fluoro-phen-yl)methanimine in diethyl ether. This compound is sensitive to air, and rapidly decomposes when exposed to air for a few minutes. The Fe atom has an octa-hedral coordination geometry in which the bidentate fluoro-phenyl methanimine...

Through a diffusion reaction, cuprous bromide, triphenyl-phosphane and 1,3-bis-(pyridin-4-yl)propane (bpp) were self-assembled to form the one-dimensional title compound, [Cu(2)Br(2)(C(13)H(14)N(2))(C(18)H(15)P)(2)](n). Each Cu(I) atom is coordinated by two Br atoms, one P atom from a triphenyl-phosphane ligand and one N atom from a bpp mol-ecule in a distorted tetra-hedral geometry. Two μ(2)-B...

In the title compound, C(20)H(14)ClP, the dihedral angle between the naphthyl rings is 81.77 (6)°. The crystal packing suggests weak π-π stacking inter-actions between the naphthyl rings in adjacent units [minimum ring centroid separation 3.7625 (13) Å].

The reaction of isophthaloyl chloride and methyl-bis(trimethylsilyl)phosphane under mild conditions affords high yields of m-{-C(O)-C(6)H(4)(C(O)PMe)}(2) (1,10-dimethyl-1,10-diphospha-[3.3]-metacyclophane-2,9,11,18-tetraone): the first example of a diphosphametacyclophane.

In the title compound, [AuCl(C(25)H(23)N(2)P)], the Au(I) atom is in a typical almost linear coordination environment defined by phosphane P and Cl atoms [bond angle = 175.48 (4)°]. Helical supra-molecular chains along the b axis and mediated by N-H⋯Cl hydrogen bonds feature in the crystal packing.

The synthesis, crystal structure and theoretical studies of a high-nuclear gold(i) complex stabilized by bridging aromatic phosphane ligands are reported. The complex is composed of a neutral Au10 complex unit with a horseshoe-like structure around a neutral Au6 complex unit with a distorted cubane-like structure.

A new BODIPY-phosphane was synthesized and proved to be a versatile tool for imaging organometallic complexes. It also led to easy access to a new family of theranostics, featuring gold, ruthenium and osmium complexes. The compounds' cytotoxicity was tested on cancer cells, and their cell uptake was followed by fluorescence microscopy in vitro.

We report a convenient and smooth protocol for the high-yielding synthesis of a triphosphane and an iso-tetraphosphane from a readily accessible tri(pyrazolyl)phosphane. The products are obtained from a one-pot reaction at room temperature and form complexes with the Fe(CO)(4)-fragment.
