Crystal structure of (2,2'-Bipyridyl)tricarbonylchloro(chloromercurio)molybdenum-(II)

Abstract

The crystal structure of the title compound, [(C₁₀H₈N₂)Mo(CO)₃(HgCl)Cl], has been determined at 295 K from diffractometer data, being refined by full-matrix methods to a residual of 0.08 (1407 reflections, I > σ(I)). Crystals are monoclinic, P2₁/c, a = 12.685(4), b = 12.494(4), c = 11.925(3) Ǻ, β = 118.70(2)°, Z = 4. The seven-coordinate molybdenum atom has the following bond distances: Mo-Hg, 2.700(7); <Mo-N>, 2.29(4); <Mo-C>, 1.89(4); Mo-Cl, 2.51(2).
