Crystal and molecular structure of tricarbonyl(2-methylindolyl)manganese

Abstract

The crystal and molecular structure of the title compound have been determined by X-ray diffraction methods from photographic data. Crystals are monoclinic tablets, space group C2/c, with Z= 8 in a cell with a= 25.46, b= 11.62, _c= 8.25 Å, and β= 109.8°. The structure has been solved by Patterson and Fourier methods, and refined by least-squares techniques to R 0.087 7 for 660 reflections. The manganese is bonded to the heterocyclic rina; one of the carbonyl grouos is trans to the nitrogen atom. The root-mean-square deviation from planarity for the atoms of the heterodyclic ring is 0.04 Å.
