Crystals of tetra-kis(4-iodo-phenyl)porphyrin chloro-form 0.85-solvate, C44H26I4N4·0.85CHCl3, (I), and [tetra-kis(4-iodo-phenyl)porphyrinato] zinc(II), [Zn(C44H24I4N4)], (II), reveal different modes of supra-molecular organization. I⋯I attractions provide a significant contribution to the layered inter-porphyrin arrangement in (I), wherein all mol-ecules have the same orientation. Weak axial coordinations of the I atoms to the Zn centres appear to have a dominant effect on the formation of two-dimensional supra-molecular assemblies in (II), with a herring-bone arrangement of the metalloporphyrin species. Both mol-ecules are located on inversion centres.
