Cis-[1,2-Bis(diphenyl-arsan-yl)ethane-?As,As']tetra-carbonyl-chromium(0).

ABSTRACT: In the title compound, [Cr(C(26)H(24)As(2))(CO)(4)], the Cr atom is octa-hedrally coordinated by four carbonyl ligands and one bidentate 1,2-bis-(diphenyl-arsan-yl)ethane ligand, which chelates in a cis manner with an As-Cr-As bite angle of 82.513?(9)°. The dihedral angles between the pairs of benzene rings attached to each As atom are 84.63?(9) and 77.15?(8)°. In the crystal, mol-ecules are linked by C-H?O inter-actions, forming infinite chains along the a axis. The crystal structure is further stabilized by C-H?? inter-actions.
