Crystal Structure and Catalytic Properties of Tetrakis (4-hydroxyphenyl) Porphyrinato Manganese (III) Chloride (MnTHPPCI)

The crystal structure of meso-tetrakis (4-hydroxyphenyl) porphyrinato manganese chloride (MnTHPPCI) and its supramolecular architecture based on the hydrogen bonds of one counter Cl anion with four hydrogen atoms of four-OH groups from different MnTHPPCI molecules cooperated by self-assembly of the porphyrin units were first reported. This compound crystallized in the tetragonal space group I4/m with a = 1. 39928(7) nm, b = 1. 39928(7) nm, c = 0. 94498(10) nm, V = 1. 8503(2) nm3, and Z = 2. As a catalyst, MnTHPPCI also showed a high catalytic activity in the conversion from 1-naphthylamine (1-NA) to bis (4-oxo-benzo-2-cyclohexen-1-yl) amine (BOBCHA) via oxidative coupling under mild conditions.
