, showing hydrogen-bonding scheme in the layer formed by base molecules. N—H⋯O hydrogen bonds between the base molecules are shown by light-blue dotted lines, while O—H⋯O hydrogen bonds between the base and acid molecules are shown by red dotted lines. [Symmetry codes: (i) −x + 1, −y + 1, −z + 1; (ii) −x + $[{1\over 2}]$ , y + $[{1\over 2}]$ , −z + $[{1\over 2}]$ ; (iv) −x + $[{1\over 2}]$ , y − $[{1\over 2}]$ , −z + $[{1\over 2}]$ .]
