Crystal structure of (n-but-yl)[2-(2,6-di-meth-oxy-phen-yl)-6-methyl-phen-yl](2-meth-oxy-phen-yl)phospho-nium chloride monohydrate

摘要

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