Crystal structure of (methanol-κO)[5,10,15,20-tetra­kis­(2-amino­phen­yl)porphyrinato-κ(4) N]zinc(II)–chloro­form–methanol (1/1/1)

In the crystal structure of the title compound, [Zn(C(44)H(32)N(8))(CH(3)OH)]·CHCl(3)·CH(3)OH, the Zn(II) cation is coordinated by four porphyrin N and one methanol O atom within a slightly distorted square-pyramidal environment and is shifted out of the porphyrin plane towards the direction of the methanol mol­ecule. The methyl group of the coordinating methanol mol­ecule is disordered over two sets of sites. The porphyrin backbone is nearly planar and the phenyl rings are almost perpendicular to the porphyrin plane. As is typical for picket-fence porphyrins, all four ortho substituents of the meso-phenyl groups (here the amino groups) are facing to the same side of the porphyrin mol­ecule. In the crystal structure, two neighbouring porphyrin complexes form centrosymmetric dimers that are connected via O—H⋯N hydrogen bonding. With the aid of additional N—H⋯N and C—H⋯N hydrogen bonding, these dimers are stacked into columns parallel to [010] that are finally arranged into layers parallel to (001). Between these layers channels are formed where chloro­form solvent mol­ecules are located that are connected to the porphyrin complexes by weak C—H⋯Cl hydrogen bonding. There are additional cavities in the structure where some small residual electron density is found, indicating the presence of disordered methanol mol­ecules, but a reasonable model could not be refined. Therefore the contribution of the electron density associated with the methanol solvent mol­ecule was removed with the SQUEEZE procedure [Spek (2015 ▸). Acta Cryst. C71, 9–18] in PLATON. Nevertheless, the given chemical formula and other crystal data take into account the methanol solvent mol­ecule.
