Abstract

The title compound, [Pt(C42H48N4)], was obtained through metallation of the corresponding free base with PtCl2, followed by crystallization from methylene chloride/methanol. The molecule exhibits an almost planar macrocycle with an average deviation of the 24 macrocyclic atoms from their least-squares plane (24) of 0.04 Å and an average Pt-N bond length of 2.022 Å. Despite the unsymmetrical substitution pattern, there is no significant difference between distortion of the geometry at the phenyl substituted meso position and those of unsubstituted meso positions.
