Figure 4
The two-dimensional hydrogen-bonded layer in (II)[link], formed by mol­ecules joined via a combination of acid-to-acid and hydrox­yl-to-ether hydrogen bonds (dotted lines). H atoms not involved in the hydrogen bonds and the minor component of the disordered carboxylic acid group have been omitted for clarity. [Symmetry codes: (i) 1 − x, 1 − y, −z; (ii) −x, [{1\over 2}] + y, [{1\over 2}] − z; (iii) x, 1 + y, z; (iv) 1 − x, 2 − y, −z; (v) 1 + x, [{3\over 2}] − y, −[{1\over 2}] + z.]
