[5,10,15,20-Tetrakis(4-chlorophenyl)porphyrinato]bis(tributylphosphine)cobalt(III) perchlorate

In the molecule of the title compound, [Co(C(44)H(24)Cl(4)N(4)){(C(4)H(9))(3)P}(2)]ClO(4), the Co(III) centre has a slightly distorted octahedral geometry and is coordinated by four N atoms of the tetrapyrrolic ring in the equatorial positions and two phosphine ligands in the axial positions. The dihedral angles between meso-substituted chlorophenyl rings and the basic tetrapyrrolic ring are 82.66 (9), 82.16 (7), 83.97 (11) and 76.87 (8)degrees. In one of the phosphine ligands, the two terminal methyl groups are disordered over two positions with refined site-occupancy ratios of 0.70 (7):0.30 (7) and 0.66 (2):0.34 (2). In the crystal structure, molecules are linked together along the a axis by intermolecular C-H center dot center dot center dot Cl interactions. The crystal structure is further stabilized by intramolecular C-H center dot center dot center dot O and C-H center dot center dot center dot N interactions and intermolecular C-H center dot center dot center dot O and C-H center dot center dot center dot pi interactions.
