Abstract
The molecular structures of I-benzyl-2-ethyl-3-hydroxypyridin-4-one hydrate [(1), C 14 H 15 NO 2 .H 2 O], 2-ethyl-3-hydroxy-[1-(4-methylbenzyl)pyridin-4-one [(2), C 15 H 17 -NO 2 ], 2-ethyl-1-(4-fluorobenzyl)-3-hydroxypyridin-4-on [(3), C 14 H 14 FNO 2 ] and 2-ethyl-3-hydroxy-1-(4-trifluoromethylbenzyl)pyridin-4-one hemihydrate [(4), C 15 H 14 -F 3 NO 2 .0.5H 2 O] have been determined. The compounds all exhibit mutually hydrogen-bonded dimeric pairs. In the case of (1) and (2), the molecules of the dimer are symmetry related, while in (3) and (4), two independent molecules of the asymmetric unit are linked. For the hydrates (1) and (4), the dimeric pairs are linked by further hydrogen bonds through the water molecules.
