title: Syntheses, structures, and crystal packing of N-confused 5,20-diphenylporphyrin and Ag(III) complex.
abstract: Beta-unsubstituted meso partially free N-confused porphyrin, N-confused 5,20-diphenylporphyrin (NCDPP, 3), was synthesized in 7% yield by [3 + 1] condensation reaction followed by oxidation. The structures of the free base and its Ag(III) complex were elucidated by the single-crystal X-ray analyses. The Ag(III) complex was more planar than the free base and formed columnar structures stacking to each other with a 3.3 A distance in the crystal. [reaction: see text]
