The asymmetric unit of the title compound, C~12~H~13~N~3~O~2~·H~2~O, comprises two crystallographically independent organic molecules and two water molecules. There is an O—H...N hydrogen bond between each water molecule and the 2-substituted pyridyl ring of an organic molecule. The water molecules
The title salt, C~8~H~20~NO~5~ ^+^·C~7~H~4~NO~4~ ^−^·H~2~O, is composed of a 4-nitrobenzoate anion, a [2-hydroxy-1,1-bis(hydroxymethyl)ethyl]bis(2-hydroxyethyl)ammonium (NBHHP) cation and a water molecule. The three units are linked by O—H...O hydrogen bonds.
The title compound, C~23~H~19~ClN~2~O~2~, has been obtained by the reaction of (__Z__)-4-(4-chlorobenzylidene)-2-phenyloxazol-5(4__H__)-one and benzylamide. The molecules are connected by two N—H...O intermolecular hydrogen bonds to form helicoidal chains running parallel to the __c__ axis.
