Tris(biphenyl-4-yl)arsane

The asymmetric unit of title compound, C(36)H(27)As, 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 mol­ecul...

Sumario:The asymmetric unit of title compound, C(36)H(27)As, 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).
