(a) The one-dimensional hydrogen-bonded chain structure formed by the A–D heterodimer units in (I)[link], extending down b. Hydrogen-bonding associations are shown as dashed lines and non-associative H atoms have been omitted. (b) The two-dimensional hydrogen-bonded structure formed by the B–C heterodimer units in (I)[link]. (c) The composite two-dimensional hydrogen-bonded structure of (I)[link], viewed down a. Symmetry codes are as in Table 1[link].
