Abstract

In the title compound, [Zn(C44H28N4)]·C12H24O6, the ZnII ion lies on an inversion center and the asymmetric unit contains one half of a Zn(TPP) complex (TPP = 5,10,15,20-tetraphenylporphyrin dianion) and one half of a centrosymmetric 18-crown-6 molecule. The Zn(TPP) complex exhibits a nearly planar conformation of the porphyrin core [maximum deviation = 0.106 (2) Å] with an average Zn—N distance of 2.047 (2) Å. The title compound is considered as a one-dimensional polymer along [010], in which the Zn(TPP) moiety is linked to the closest O atoms of two symmetry-related 18-crown-6 molecules with a Zn—O distance of 2.582 (1) Å, completing a distorted octahedral coordination environment of the metal ion. The chains are mainly sustained by weak C—H⋯π interactions. An ethylene group of the 18-crown-6 molecule is disordered over three sites with occupancies of 0.50, 0.25 and 0.25.
