(4-Methoxybenzoylmethyl)triphenylphosphonium trifluoromethanesulfonate

Abstract

Colourless crystals of the title compound, C27H24O2P+·CF3SO3−, have been prepared by the addition of a solution of AgCF3SO3 in methanol to a solution of (4-methoxybenzoylmethyl)triphenylphosphonium bromide in dry methanol. There are two crystallographically independent molecules in the asymmetric unit. The crystal structure is stabilized by inter- and intramolecular C—H...O hydrogen bonds and further stabilized by C—H...π interactions.
