N-(2,5-Dimethyl­phen­yl)succinamic acid monohydrate

In the title compound, C(12)H(15)NO(3)·H(2)O, the conformation of the N—H bond in the amide segment is syn to the ortho-methyl group and anti to the meta-methyl group in the benzene ring. Further, the conformations of the amide O and the carbonyl O atom of the acid segment are anti to the adjacent methyl­ene H atoms. The C=O and O—H bonds of the acid group are syn to one another. The structure shows an inter­esting hydrogen-bonding pattern with the water mol­ecule forming hydrogen bonds with three different mol­ecules of the compound. In the crystal, mol­ecules are packed into infinite chains through inter­molecular O—H⋯O and N—H⋯O hydrogen bonds.
