Tris(biphenyl-4-yl)arsane

Abstract

The asymmetric unit of title compound, C36H27As, contains two crystallographically independent mol­ecules, 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 mol­ecule A and 5.7 (3), 27.5 (2) and 33.0 (2)° in mol­ecule B. The As-bonded phenyl rings make dihedral angles of 54.9 (2), 76.0 (2) and 88.2 (2),° with each other in mol­ecule A, and 60.3 (2), 78.1 (2) and 79.5 (2)° in mol­ecule B. In the crystal, the mol­ecules are stacked down the b axis. Weak inter­molecular C—H⋯π inter­actions 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 phenyl rings of biphenyl (C26-C31/C32-C37, C38-C43/C44-C49 and C50-C55/C56-C61) make dihedral angles of 50.5 (2), 44.5 (2) and 27.8 (2)° from each other respectively. These angles are more twisted from each other compare to the reported monodentate arsine ligand (Shawkataly et al, 2011). The arsine-substituted phenyl rings make dihedral angles (C26-C31/C38-C43, C26-C31/C50-C55 and C38-C43/C50-C55) of 61.56 (18), 89.36 (18) and 83.27 (18)° with each other respectively.…”

“…Additionally, each Ru atom carries one equatorial and two axial terminal carbonyl ligands (Fig 1). The conformation of the title compound is very identical to its closely related structure (Shawkataly et al, 2011b). Both phenyl rings of biphenyl (C26-C31/C32-C37, C38-C43/C44-C49 and C50-C55/C56-C61) make dihedral angles of 51.22 (18), 42.94 (16) and 26.95 (16)° from each other respectively are more twisted from each other compare to the reported monodentate arsine ligand (Shawkataly et al, 2011a).…”
