چکیده
In the title compound, [Zn(C44H28N4)]·C12H24O6, the Zn(II) ion lies on an inversion center and the asymmetric unit contains one half of a Zn(TPP) complex (TPP = 5,10,15,20-tetra-phenyl-porphyrin dianion) and one half of a centrosymmetric 18-crown-6 mol-ecule. 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 mol-ecules 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 inter-actions. An ethyl-ene group of the 18-crown-6 mol-ecule is disordered over three sites with occupancies of 0.50, 0.25 and 0.25.
