Abstract :
The title hydrate, C13H14N2O4·H2O, crystallizes with two formula units in the asymmetric unit (Z′ = 2). The dihedral angles between the planes of the tetrahydropyrimidine ring and the 4-hydroxyphenyl ring and ester group are 86.78 (4) and 6.81 (6)°, respectively, for one molecule and 89.35 (4) and 3.02 (4)° for the other. In the crystal, the organic molecules form a dimer, linked by a pair of N—H⋯O hydrogen bonds. The hydroxy groups of the organic molecules donate O—H⋯O hydrogen bonds to water molecules. Further, the hydroxy group accepts N—H⋯O hydrogen bonds from amides whereas the water molecules donate O—H⋯O hydrogen bonds to the both the amide and ester carbonyl groups. Other weak interactions, including C—H⋯O, C—H⋯π and π–π, further consolidate the packing, generating a three-dimensional network
