چکیده
The title compound, C21H15O4P·0.5C4H8O, contains an ordered phosphane oxide in a general position and a tetra-hydro-furan solvent mol-ecule disordered about a twofold axis. All three aldehyde substituents are nearly coplanar with their attached benzene rings, with C-C-C-O torsion angles in the range 1.64 (17)-4.24 (19)°. All three have different conformations with respect to the P=O group, one syn, one anti, and one gauche. Two of the aldehyde substituents form inter-molecular C-H⋯O contacts.

The title compound, P(C10H7)3·0.5CHCl3, was isolated after the unsuccessful reaction of KSeCN and tris-(naphthalen-1-yl)phosphane. The solvent mol-ecule is disordered about an inversion center. The effective cone angle of the phosphine is 203°. In the crystal, weak C-H⋯Cl and C-H⋯π inter-actions are observed.

A series of tris-aryl phosphane oxides existing as residual enantiomers or diastereoisomers with substituents on the aryl rings differing in size and electronic properties were synthesized and characterized. Their electronic properties were evaluated on the basis of their electrochemical oxidation and reduction potentials together with those of the corresponding "blade bromides" (i.e., the naph...

The crystal structures of two solvates of fac-tri-chlorido-tris-(tri-methyl-phosphane-κP)rhodium(III) are reported, i.e. one with water in the crystal lattice, fac-[RhCl3(Me3P)3]·H2O, and one with methanol in the crystal lattice, fac-[RhCl3(Me3P)3]·0.5CH3OH. These rhodium compounds exhibit distorted octahedral coordination spheres at the metal and are isotypic with the analogous iridium compoun...

In the mononuclear title compound, [Tb(C(13)H(9)OS(3))(3)(C(4)H(8)O)(3)]·C(4)H(8)O, the lanthanide cation is located on a threefold rotation axis and is surrounded by electron-rich ligands in an approximately octa-hedral geometry. One of the thienyl groups and the bound THF are disordered with 0.5:0.5 occupancy. The free THF is disordered around the threefold axis.

The title compound, [PtCl(C(42)H(78)OP(4))]Cl·0.5CH(2)Cl(2)·4H(2)O, crystallizes as a contact ion-pair with two close inter-molecular C-H⋯Cl(-) contacts between CH acidic αH atoms of the phosphane ligand and the chloride anion. A chloride ligand together with three coordinating P ligand atoms create a slightly distorted square-planar coordination environment around the Pt(II) center. An inter-m...
