摘要：

The structure of nitrosyl(sulfur dioxide)bis(triphenylphosphine)cobalt has been determined by single-crystal X-ray techniques. The coordination about the cobalt atom is approximately tetrahedral, with coplanar, sulfur-bound M-S02 geometry and a linear nitrosyl group. In contrast, the isoelectronic complex Rh(N0)(SO2)(PPh3)2 exhibits a bent nitrosyl group and an η2-SO2 coordination in which the sulfur and one oxygen are approximately equidistant from the rhodium atom. The difference between these two complexes may be attributed to differences in metal basicity. The title complex crystallizes in the space group P2/c with lattice parameters of a = 20.494 (13) Å, b = 10.146 (6) Å, c = 17.693 (11) Å, and β = 119.78 (4)° with Z = 4. The Co-S distance is 2.021 (8) β while the Co-N distance is 1.68 (1) β. The M-N-O angle is 169 (2)°. The dihedral angle between the plane defined by the Ni, S, and N atoms and that defined by the SO2 is 20.1°. © 1979, American Chemical Society. All rights reserved.
