Metalation of 6,13,20,21-tetrakis(4-methyl-phenyl)-22H-tribenzo[14]triphyrin(2.1.1) with PtCl2 gave a platinum(II) complex having a square-planar coordination structure with two pyrrolic nitrogen atoms and two chloride ions, with a saddle-shaped macrocycle. This platinum(II) complex was easily oxidized by air to an octahedral platinum(IV) complex coordinated by three pyrrolic nitrogen atoms as a tridentate monoanionic cyclic ligand and three chloride ions. When platinum(II) triphyrin was crystallized in air, an oxygen atom was incorporated between two alpha-carbon atoms of the pyrroles as an oxygen bridge to intercept the 14 pi aromatic system.
