Abstract

The crystal structure of [Mn(TPP)Cl] in space group I4/m (where TPP is C44H28N4) has been determined. The unit cell contains two full molecules, with one eighth of a molecule unique. An out-of-plane model for the Mn atom was applied and all non-H atoms were refined anisotropically. The Mn--N distance is 2.002 (3) A, the axial Mn--Cl distance is 2.297 (15) A and the out-of-plane displacement of the Mn atom is 0.16 A. The possibility of a reverse-doming porphyrin core conformation is mentioned briefly.
