Abstract
The title compound, [Cd(C44H28N4)(H2O)]·(C12H24O6), was made by the reaction of the [Cd(TPP)] with an excess of 18-crown-6 in chlorobenzene (where TPP is tetraphenylporphyrinate). The CdII cation is chelated by a TPP anion and coordinated by a water molecule in a distorted N4O square-pyramidal geometry, the CdII cation being displaced by 0.7533 (9) Å from the mean plane of four N atoms of TPP anion. The porphyrin core presents a significant distortion, the maximum atomic deviation from the 24-atom mean plane is 0.1517 (2) Å. The 18-crown-6 molecule is linked with the CdII complex via classical O—H⋯O hydrogen bonds. In the crystal, weak C—H⋯π interactions link the complex and 18-crown-6 molecules into a three-dimensional supramolecular architecture.
