title: 1,3-Bis(2,6-diisopropyl-anilino)-1-phenyl-butyl-ium hexa-fluorido-phosphate.
abstract: The cation of the title salt, C(34)H(45)N(2) (+)·PF(6) (-), is a protonated form of an unsymmetrical overcrowded β-imino-amine. The observed bond lengths [C-N = 1.326 (4)-1.341 (4) Å and C-C = 1.383 (4)-1.391 (4) Å] suggest significant delocalization within the π system of the N C C C N backbone.
