Abstract
The title complex, [Cu(C68H44N4)]·C2H2Cl4, exhibits nearly square-planar geometry around the CuII centre and the macrocyclic ring is almost planar. The porphyrin molecule has an approximate non-crystallographic inversion centre (Ci), and a non-crystallographic twofold rotation axis (C 2) within the CuII–porphyrin ring plane. Further, it has non-crystallographic twofold rotation axis and mirror plane (Cs) symmetry perpendicular to the molecular plane. The molecular packing of the complexes and the solvent molecules shows weak intermolecular C—H⋯π, C—H⋯Cl and C—H⋯N interactions, forming a clathrate-like structure.
