Crystal structure of (n-butyl)[2-(2,6-dimethoxyphenyl)-6-methylphenyl](2-methoxyphenyl)phosphonium chloride monohydrate

Abstract

The title hydrated salt, C26H32O3P+·Cl−·H2O, contains four different substituents (H, alkyl, aryl, and biaryl) on the P atom. The P—H hydrogen atom of the phosphonium ion was located in a difference Fourier map and refined without imposing additional restraints. In the crystal, the Cl−ions and water molecules are linked by pairs of Owater—H...Cl−hydrogen bonds and further linked to the phosphonium cation by P—H+...Cl−and CAr/OMe—H...Owaterhydrogen bonds to form an infinite one-dimensional chain along the [010] direction.
