The reaction of [Co(III)(TPP)Cl] (TPP is the dianion of 5,10,15,20-tetra-phenyl-porphyrin) with an excess of 4-nitro-aniline in di-chloro-methane leads to the title compound, [Co(III)(C44H28N4)(C6H6N2O2)2]Cl·CH2Cl2. The Co(III) ion lies on an inversion centre and is octa-hedrally coordinated by two N atoms of the NH2 groups of the two 4-nitro-aniline trans-axial ligands and four pyrrole N atoms of the porphyrin. The asymmetric unit contains one half of the [Co(III)(TPP)(4-nitro-aniline)2](+) ion complex, one chloride counter-ion (lying on a twofold rotation axis) and one half di-chloro-methane solvent mol-ecule, where the C atom lies on a twofold rotation axis.

The asymmetric unit of the title compound, [Co(C(36)H(44)N(4))]·2C(7)H(5)NO(3), is composed of one half of the complex, arranged about an inversion center, and a complete 2-nitro-benzaldehyde (NBA) mol-ecule. The structure consists of columns that contain inter-leaved mol-ecules of NBA and [Co(II)(OEP)] (OEP is 2,3,7,8,12,13,17,18-octa-ethyl-porphyrin), which are stacked along the a axis. The Co(II) atom is involved in a π inter-action with the ring of the NBA mol-ecule with a centroid-metal distance of 3.

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.
