In methanolic solutions, disproportionation of the TCNQ anion radical to neutral TCNQ0 and the dianion TCNQ2- followed by aerobic oxidation of TCNQ2- results in the formation of methyl-4-dicyanomethylene benzoate anion (MDCB-). This anion coordinates to the manganese(III) atom of 5,10,15,20-tetraphenylporphinatomanganese(III) leading to the complex whose X-ray crystal structure is reported. The crystal had the monoclinic space group P21/n with unit cell dimensions a = 13.327(3), b = 20.236(6), c = 16.914(5) Å and β = 92.26(2)°. An important driving force behind the crystal packing is a hydrogen bonding interaction between non-identical ligands of adjacent molecules. © 2001 Elsevier Science B.V.
