2,4,5-Trimethoxybenzaldehyde monohydrate

Abstract

In the title compound, C10H12O4·H2O, the 2,4,5-trimethoxybenzaldehyde molecule is almost planar (rms deviation = 0.0183 Å). There is an R12(5) ring motif due to O—H...O hydrogen bonding. In the crystal, the molecules are stabilized in the form of one-dimensional polymeric chains extending along [010] due to O—H...O hydrogen bonding with adjacent water molecules. The H atoms involved in intermolecular hydrogen bonding are disordered over two sets of sites of equal occupancy.
