In the title compound, [K(C18H36N2O6)][Co(NCO)2(C44H28N4)]·0.5C6H5Cl or [K(2,2,2-crypt)+][CoIII(NCO)2(TPP)-]·0.5C6H5Cl, the CoIII ion is octa­hedrally coordin­ated 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 mol­ecule 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...[pi] inter­actions. The contribution to the scattering of the disordered chloro­benzene solvent mol­ecules was removed with the SQUEEZE function in PLATON [Spek (2009). Acta Cryst. D65, 148-155].
