, contains one half of a Co
II
(TPP) (TPP is tetraphenylporphyrin) complex and one half of an 18-crown-6 molecule of crystallization, both lying on inversion centers. The Co
II
(TPP) complex exhibits a nearly planar conformation of the porphyrinate core [maximum deviation = 0.069 (2) Å] with an average Co—N distance of 1.971 (4) Å. The distance between the Co atom and the closest O atom of the 18-crown-6 molecule is 2.533 (2) Å, indicating a short non-bonded contact between the Co atom and the crown ether molecule. An ethylene group of the 18-crown-6 molecule is disordered over two sites with occupancies of 0.565 (7) and 0.435 (7).
