A study of the pyramidality index in tris­(2,4,6-triiso­propyl­phen­yl)phos­phonium perchlorate

R. T. Boeré and Y. Zhang

Synopsis: This is the most sterically congested tri­aryl­phospho­nium salt yet to be reported and has a `propeller' arrangement of the three 2,4,6-triiso­propyl­phenyl groups around the P atom, with the protonation site located along the mol­ecular threefold axis. There are short P...H contacts between the flanking isopropyl methine H atoms and the P atom.

Formula: C45H70P+·ClO4-
