Tris(biphenyl-4-yl)arsane.

ABSTRACT: The asymmetric unit of title compound, C(36)H(27)As, contains two crystallographically independent mol-ecules, A and B, with similar conformations. The two phenyl rings of each biphenyl unit are twisted slightly away from each other with dihedral angles of 6.0?(2), 27.7?(3) and 33.4?(2)° in mol-ecule A and 5.7?(3), 27.5?(2) and 33.0?(2)° in mol-ecule B. The As-bonded phenyl rings make dihedral angles of 54.9?(2), 76.0?(2) and 88.2?(2),° with each other in mol-ecule A, and 60.3?(2), 78.1?(2) and 79.5?(2)° in mol-ecule B. In the crystal, the mol-ecules are stacked down the b axis. Weak inter-molecular C-H?? inter-actions stabilize the crystal structure. The crystal studied was a racemic twin, the refined ratio of twin components being 0.461?(7):0.539?(7).

The two phenyl rings of each biphenyl unit are twisted slightly away from each other with dihedral angles of 6.0 (2), 27.7 (3) and 33.4 (2)° in mol-ecule A and 5.7 (3), 27.5 (2) and 33.0 (2)° in mol-ecule B. The As-bonded phenyl rings make dihedral angles of 54.9 (2), 76.0 (2) and 88.2 (2),° with each other in mol-ecule A, and 60.3 (2), 78.1 (2) and ...[more]

Project description:In the title triangulo-triruthenium compound, [Ru(3)(C(36)H(27)As)(C(25)H(22)P(2))(CO)(9)], the bis-(diphenyl-phosphan-yl)methane ligand bridges an Ru-Ru bond and the monodentate arsine ligand bonds to the third Ru atom. Both the arsine and phosphine ligands are equatorial with respect to the Ru(3) triangle. In addition, each Ru atom carries one equatorial and two axial terminal carbonyl ligands. In each biphenyl unit, the phenyl rings are twisted from each other, making dihedral angles of 51.22 (18), 42.94 (16) and 26.95 (16)°. The arsine-substituted phenyl rings make dihedral angles of 61.22 (15), 87.17 (15) and 83.32 (15)° with each other. The dihedral angles between the two benzene rings are 85.52 (18) and 81.77 (15)° for the two diphenyl-phosphanyl groups, respectively. In the crystal, mol-ecules are linked into dimers by inter-molecular C-H⋯O hydrogen bonds. Weak inter-molecular C-H⋯π and π-π [centroid-centroid distance = 3.6981 (18) Å] inter-actions stabilize the crystal structure.

Project description:The title compound, [Sm(2)(C(14)H(8)O(4))(3)(H(2)O)(2)](n), is composed of one-dimensional chains and is isostructural with previously reported compounds [Wang et al. (2003 ?). Eur. J. Inorg. Chem. pp. 1355-1360]. The asymmetric unit contains two Sm atoms, each of which lies on a crystallographic twofold axis. Both crystallographically independent Sm atoms are coordinated by eight O atoms in a distorted dodeca-hedral arrangement. The polymeric chains run along [001]. Adjacent chains are connected through ?-? inter-actions [centroid-centroid distance = 3.450?(2)?Å], forming a two-dimensional supra-molecular network.
