{5,15-Bis[3,5-bis-(6'-methyl-2,2'-bipyridyl-6-yl)phen-yl]-10,20-di-phenyl-porphyrin}zinc(II) 1,2-di-meth-oxy-ethane...

In the title compound, [Zn(C₈₈H₆₀N₁₂)]·0.296C₄H₁₀O₂, the porphyrin macrocycle is essentially planar, with the Zn atom located in the plane on an inversion centre. The non-substituted and bi-pyridine-bearing phenyl rings are twisted with respect to the porphyrin plane by 65.55 (6) and 64.85 (7)°, respectively. The phenyl and pyridine rings are moderately twisted, with dihedral angles of 21.21 (17) and 30.33 (14)°. The bi-pyridine moieties adopt an s-trans conformation with dihedral angles of 17.52 (18)° and 13.92 (13)°. The bi-pyridine units are located on both sides of the porphyrin plane due to the substitution at the 3- and 5-positions of the meso-phenyl ring. One bi-pyridine moiety folds back towards the porphyrin, while the other extends away from the porphyrin. π-π inter-actions between the porphyrin plane and the terminal pyridine ring of the extended bi-pyridine propagate along the [011] and [011] directions within the bc plane. The folded bi-pyridine units project from the network, resulting in alternating layers. The folded bi-pyridine layer contains void channels that are partially occupied by the crystallization solvent, 1,2-di-meth-oxy-ethane.
