The nature of supramolecular interactions in tetrakis(4-iodophenyl)porphyrin and its zinc(II) complex.
Crystals of tetrakis(4-iodophenyl)porphyrin chloroform 0.85-solvate, C(44)H(26)I(4)N(4) x 0.85CHCl(3), (I), and [tetrakis(4-iodophenyl)porphyrinato]zinc(II), [Zn(C(44)H(24)I(4)N(4))], (II), reveal different modes of supramolecular organization. I...I attractions provide a significant contribution to the layered interporphyrin arrangement in (I), wherein all molecules 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 supramolecular assemblies in (II), with a herring-bone arrangement of the metalloporphyrin species. Both molecules are located on inversion centres.
