Crystal structure of (diethyl ether-κO)[5,10,15,20-tetra­kis­(2-iso­thio­cyanato­phen­yl)porphyrinato-κ4N]zinc diethyl ether solvate

The crystal structure of the title compound, [Zn(C48H24N8S4)(C4H10O)]·C4H10O, consists of discrete porphyrin complexes that are located on a twofold rotation axis. The ZnII cation is fivefold coordinated by four N atoms of the porphyrin moiety and one O atom of a diethyl ether mol­ecule in a slightly distorted square-pyramidal environment with the diethyl ether mol­ecule in the apical position. The porphyrin backbone is nearly planar with the metal cation slightly shifted out of the plane towards the coordinating diethyl ether mol­ecule. All four iso­thio­cyanato groups of the phenyl substituents at the meso-positions face the same side of the porphyrin, as is characteristic for picket fence porphyrins. In the crystal structure, the discrete porphyrin complexes are arranged in such a way that cavities are formed in which additional diethyl ether solvate mol­ecules are located around a twofold rotation axis. The O atom of the solvent mol­ecule is not positioned exactly on the twofold rotation axis, thus making the whole mol­ecule equally disordered over two symmetry-related positions.
