Abstract
The asymmetric unit of the title compound, [Ni(C52H34Cl4N4O4)]·CH2Cl2, consists of two discrete complexes, which show significant differences in the conformation of the side chain. Each NiII cation is coordinated by four nitrogen atoms of a porphyrin molecule within a square-planar coordination environment. Weak intramolecular C—H...Cl and C—H...O interactions stabilize the molecular conformation. In the crystal structure, discrete complexes are linked by C—H...Cl hydrogen-bonding interactions. In addition, the two unique dichloromethane solvate molecules (one being disordered) are hydrogen-bonded to the Cl atoms of the chlorophenyl groups of the porphyrin molecules, thus stabilizing the three-dimensional arrangement. The crystal exhibits pseudo-orthorhombic metrics, but structure refinements clearly show that the crystal system is monoclinic and that the crystal is twinned by pseudo-merohedry.
