1-(2-Methyl-imidazo[1,2-a]pyridin-3-yl)-3,3-bis-(methyl-sulfan-yl)prop-2-enone monohydrate.

The title compound, C(13)H(14)N(2)OS(2)·H(2)O, appears in the form of bimolecular aggregate in which mol-ecular components are linked by O-H⋯N hydrogen bonding. The nine-membered imidazo[1,2-a]pyridine system is almost planar, with a mean deviation of 0.026 (1) Å. An intra-molecular C-H⋯O hydrogen bond forms within the imidazo[1,2-a]pyridine system. The crystal packing is consolidated by O-H⋯O and C-H⋯O hydrogen bonds, forming a supra-molecular structure consisting of perpendicular infinite mol-ecular chains running along the a and c axes.
