Carbon compounds of the transition metals. Part XXVIII. Crystal structure of bromotriscarbonyl(phenyl isocyanide)manganese(I)
Abstract
The crystal structure of the title compound has been determined from 555 visually estimated X-ray reflexions and refined by least-squares techniques to R 11·1. Crystals are monoclinic, space group P21/n, with a= 18·03, b= 5·93, c= 16·83 Å, β= 107·33°, and Z= 4. The co-ordination about the manganese is close to regular octahedral with the two isonitrile groups mutually cis and the bromine trans to a carbonyl group. The groups Mn–C–O and Mn–C–N–Ph are linear. Mean bond lengths are: Mn–Br 2·527(8), Mn–CO 1·74(3), Mn–CN 1·92(3), C–O 1·17(3), and C–N 1·12(3)Å.
