Pt(II) N-confused porphyrin: An expanded pyrrole that affords a stable π-anion

Pt(II) complex of meso-tetrakis(pentafluorophenyl) N-confused porphyrin (1-Pt) efficiently binds Cl(-), Br(-), and I(-) anions at the peripheral N-H, while deprotonation proceeds with F(-), H(2)PO(4)(-), and OH(-) in CH(2)Cl(2) solution; neutral and anionic structures of 1-Pt were characterized by single crystal X-ray diffraction analysis.
