ABSTRACT 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 methyl-ene H atoms. The C=O and O-H bonds of the acid group are syn to one another. The structure shows an inter-esting hydrogen-bonding pattern with the water mol-ecule forming hydrogen bonds with three different mol-ecules of the compound. In the crystal, mol-ecules are packed into infinite chains through inter-molecular O-H⋯O and N-H⋯O hydrogen bonds.

    ABSTRACT: In the title compound, C(10)H(9)Cl(2)NO(3), the conformation of the N-H bond in the amide segment is syn with respect to the ortho-Cl atom and anti to the meta-Cl atom of the benzene ring. In the crystal, inter-molecular O-H⋯O and N-H⋯O hydrogen bonds pack the mol-ecules into two types of chains along the a and b axes, respectively, leading to an overall sheet structure. The acid group in the side chain is disordered and was refined using a split model with site-occupation factors of 0.60:0.40.
