Stable Platinum(IV) Corroles: Synthesis, Molecular Structure, and Room-Temperature Near-IR Phosphorescence.

ABSTRACT: A series of stable Pt(IV) corrole complexes with the general formula Pt^IV[TpXPC](m/p-C₆H₄CN)(py), where TpXPC^3- is the trianion of a tris(p-X-phenyl)corrole and X = CF₃, H, and CH₃, has been synthesized, affording key physicochemical data on a rare and elusive class of metallocorroles. Single-crystal X-ray structures of two of the complexes revealed very short equatorial Pt-N distances of 1.94-1.97 Å, an axial Pt-C distance of ∼2.03 Å, and an axial Pt-N distance of ∼2.22 Å. The complexes exhibit Soret maxima at ∼430 nm, which are essentially independent of the meso-aryl para substituents, and strong Q bands with the most intense peak at 595-599 nm. The substituent-independent Soret m
