(2.2.2-Cryptand)potassium bis-(cyanato-?N)(5,10,15,20-tetra-phenyl-por-phy-rin-ato-?(4)N)cobaltate(III) chloro-benzene hemisolvate.

ABSTRACT: In the title compound, [K(C(18)H(36)N(2)O(6))][Co(NCO)(2)(C(44)H(28)N(4))]·0.5C(6)H(5)Cl or [K(2,2,2-crypt)(+)][Co(III)(NCO)(2)(TPP)(-)]·0.5C(6)H(5)Cl, the Co(III) ion is octa-hedrally coordin-ated by two axial N-bonded NCO(-) anions and four pyrrole N atoms of the porphyrin. There is a major ruffling distortion of the porphyrin: the dihedral angles between trans pyrrole rings are 34.32?(14) and 34.72?(14)°. The potassium ion is coordinated by the six O atoms and two N atoms of the cryptand-222 mol-ecule and a weak K-O [3.407?(3)?Å] bond to one of the cyanate O atoms also occurs. The packing also features weak C-H?O and C-H?? inter-actions. The contribution to the scattering of the disordered chloro-benzene solvent mol-ecules was removed with the SQUEEZE function in PLATON [Spek (2009 ?). Acta Cryst. D65, 148-155].
