A redetermination of (2-methoxyphenyl)diphenylphosphine
The asymmetric unit of the title triphenylphosphine compound, C19H17OP, consists of two crystallographically independent molecules with similar conformations. One of these two molecules has a whole-molecule disorder over two positions with refined occupancies of 0.753 (3) and 0.247 (3). The dihedral angles between the three benzene rings are 89.69 (7), 76.54 (7) and 86.02 (7)° in the non-disordered molecule and the corresponding angles are 88.3 (4), 83.2 (4) and 84.2 (3)° for the major component and 80.2 (11), 89.5 (11) and 74.4 (9)° for the minor component of the disordered molecule. This structure has been reported previously [Suomalainen et al. (2000 ▶). Eur. J. Inorg. Chem. pp. 2607–2613]; however, the disorder detailed here was not mentioned in that determination. In the crystal structure, the molecules are stacked down the b axis and stabilized by C—H⋯π interactions
Undecacarbonyl-1κ3 C,2κ4 C,3κ4 C-[tris(3-chlorophenyl)phosphine-1κP]-triangulo-triruthenium(0)
In the title triangulo-triruthenium compound, [Ru3(C18H12Cl3P)(CO)11], one equatorial carbonyl group has been substituted by the monodentate phosphine ligand, leaving one equatorial and two axial carbonyl substituents on the Ru atom. The remaining two Ru atoms each carry two equatorial and two axial terminal carbonyl ligands. The three benzene rings make dihedral angles of 87.83 (17), 69.91 (17) and 68.26 (17)° with each other. In the crystal structure, molecules are linked into dimers by intermolecular C—H⋯O hydrogen bonds. The molecular structure is stabilized by an intramolecular C—H⋯O hydrogen bond
Decacarbonyl-1κ3 C,2κ3 C,3κ4 C-bis[tris(3-chlorophenyl)phosphine]-1κP,2κP-triangulo-triruthenium(0) monohydrate
The asymmetric unit of the title triangulo-triruthenium compound, [Ru3(C18H12Cl3P)2(CO)10]·H2O, consists of one triangulo-triruthenium complex and one disordered water solvent molecule. Two of the 3-chlorophenyl rings are disordered over two positions with refined site occupancies of 0.671 (3)/0.329 (3) and 0.628 (3)/0.372 (3). The water molecule is disordered over two positions with refined site occupancies of 0.523 (7) and 0.477 (7). Two equatorial carbonyl groups have been substituted by the two monodentate phosphine ligands, leaving one equatorial and two axial carbonyl substituents on the two Ru atoms. The remaining Ru atom carries two equatorial and two axial terminal carbonyl ligands. In the crystal structure, molecules are linked into columns along the a axis by intermolecular C—H⋯Cl and C—H⋯O hydrogen bonds. The molecular structure is stabilized by weak intramolecular C—H⋯O hydrogen bonds
Tris(2-methoxyphenyl)phosphine
In the title compound, C21H21O3P, the whole molecule is disordered over two sets of positions with refined occupancies of 0.503 (1) and 0.497 (1). The dihedral angles between the three benzene rings are 72.9 (2)°, 82.9 (3)° and 70.0 (2)° in the major disorder component and the corresponding angles in the minor disorder component are 85.0 (2)°, 79.2 (2)° and 72.3 (2)°. The crystal structure is stabilized by C—H⋯π interactions
Tris[3,5-bis(trifluoromethyl)phenyl]phosphine oxide
In the title compound, C24H9F18OP, an intramolecular C—H⋯O short contact generates a five-membered ring, producing an S(5) ring motif. The dihedral angles between the benzene rings are 57.68 (10), 77.80 (11) and 79.48 (10)°. Each of the six trifluoromethyl substituents shows rotational disorder over two positions with refined site-occupany ratios of 0.64 (3)/0.36 (3), 0.649 (14)/0.351 (14), 0.52 (2)/0.48 (2), 0.545 (16)/0.455 (16), 0.774 (9)/0.226 (9) and 0.63 (5)/0.37 (5). The crystal structure is stabilized by intermolecular C—H⋯O and C—H⋯F interactions
[1,3-Bis(diphenylphosphino)pentane-κ2 P,P′]tetracarbonylchromium(0)
In the title compound, [Cr(C29H30P2)(CO)4], the Cr atom is octahedrally coordinated by four carbonyl ligands and one bidentate phosphine ligand, which is bounded as a chelate in a cis position. The average Cr—P and Cr—C bond lengths are 2.377 and 1.865 Å, respectively
