Dibromo[5,10,15,20-tetrakis(4-methoxyphenyl)porphyrinato-kappa 4N]platinum(IV) chloroform acetonitrile solvate.
In the title compound, [PtBr(2)(C(48)H(36)N(4)O(4))].0.896CHCl(3).0.569CH(3)CN, the centrosymmetric metal complex is octahedral, with the porphyrin ring essentially planar and the Br atoms occupying axial positions. The two independent methoxyphenyl substituents are tilted at angles of 89.0 and 67.0 degrees with respect to the porphyrin plane. The Pt-N distances are 2.035 (4) and 2.036 (4) A and the Pt-Br distance is 2.4666 (6) A. Chloroform and acetonitrile solvent molecules, exhibiting substantial disorder, occupy positions between the porphyrin molecules. This is the first crystal and molecular structure of a Pt(IV)-porphyrin complex to be reported.
