Nafimidone monohydrate: an imidazole anticonvulsant

A. Hempel, N. Camerman, A. Camerman and D. Mastropaolo

Abstract: In the crystal structure of 2-(1H-imidazol-1-yl)-1-(2-naphthyl)ethanone monohydrate, C₁₅H₁₂N₂O·H₂O, the naphthalene and imidazole rings are essentially planar and the angle between their planes is 77.05 (11)°. The water molecule connects two nafimidone molecules through O-HN and O-HO hydrogen bonds [HN 1.83 (5) and HO = 2.14 (6) Å], creating centrosymmetric dimer clusters. Weak non-standard hydrogen bonds of the type C-HO [HO 2.53-2.60 Å] also contribute to the crystal packing.
