title: (2,3,7,8,12,13,17,18-Octa-ethyl-5-phenyl-porphyrinato)platinum(II).
abstract: The title compound, [Pt(C(42)H(48)N(4))], was obtained through metallation of the corresponding free base with PtCl(2), followed by crystallization from methyl-ene chloride/methanol. The mol-ecule exhibits an almost planar macrocycle with an average deviation of the 24 macrocyclic atoms from their least-squares plane (Δ24) 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.
