Figure 2
Fragments of the crystal structures of (I)[link] and (II)[link], representing the hydrogen-bonding and structural motifs. Hydrogen bonds are shown as dashed lines, and H atoms of the CH2 and CH3 groups have been omitted. (a) An R44(20) ring motif in (I)[link] [symmetry code: (i) −x, −y + 1, −z + 1]. (b) A C22(10) infinite chain in (II)[link], extending along the crystallographic c axis, and the O—H⋯O hydrogen bonds formed by water mol­ecules, which function as bridges between these chains [symmetry codes: (iii) x, −y + 1, z − [{1\over 2}]; (iv) x, y, z − 1; (v) x, −y + 2, z − [{1\over 2}]].
