Phosphonium ylides as hydrogen bond acceptors: intermolecular C–H⋯C interactions in the crystal structure of triphenylphosphonium benzylide
Abstract
A pairwise alignment of molecules in the crystal structure of the title ylide suggests the existence of mutual C–H⋯C interactions between acidic o-Ph groups of one molecule and the basic carbanionoid centre of the other, an interpretation which is supported by examination of previously reported X-ray data.
