title: (5,10,15,20-Tetra-phenyl-porphyrinato-κN)cobalt(II)-18-crown-6 (1/1).
abstract: The asymmetric unit of the title compound, [Co(C(44)H(28)N(4))]·C(12)H(24)O(6), contains one half of a Co(II)(TPP) (TPP is tetra-phenyl-porphyrin) complex and one half of an 18-crown-6 mol-ecule 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 mol-ecule is 2.533 (2) Å, indicating a short non-bonded contact between the Co atom and the crown ether mol-ecule. An ethyl-ene group of the 18-crown-6 mol-ecule is disordered over two sites with occupancies of 0.565 (7) and 0.435 (7).
