A di­methyl sulfoxide/chloro­form clathrate of (di­methyl sulfoxide)(tetra­phenyl­porphyrinato)­zinc(II)

The title compound, [Zn(C₄₄H₂₈N₄)(C₂H₆OS)]·0.79C₂H₆OS·0.21CHCl₃, crystallizes as a sulfoxide–chloro­form true clathrate. The main residue, (di­methyl sulfoxide)(tetra­phenyl­porphyrinato)­zinc(II), is a five-coordinate zinc–porphyrin complex, with di­methyl sulfoxide as an axial ligand. The crystal structure is characterized by a typical layered organization of the porphyrin species, with the solvent guest molecules intercalated between the layers.
