Crystal structure of fac-chloro-[1,3-bis(dimethylarsino)propane]tricarbonylmanganese

Abstract

Crystals of the title compound are orthorhombic, a= 15·279, b= 15·445, c= 13·982 Å, Z= 8, space group Pbca. The structure was determined from diffractometer data by Patterson and Fourier methods, and refined by full-matrix least-squares techniques to R 0·116 for 783 observed reflections. The conformation found is that which shows the least interaction between the axial methyl group of the arsenic atoms and the substituents of the metal atom.
