Figure 3
The hydrogen-bonding assembly mode in (II)[link], showing the fexofenadine dimer solvated by mol­ecules of water (shown as small spheres), and further hydrogen bonding of this dimer to neighbouring mol­ecules through atoms O2 and O3 [only the major disordered site (O2A) is shown; see also Table 4[link]]. The dimer consists of mol­ecules related by inversion at ([1, 0, {1 \over 2}]). H atoms have been omitted for clarity, except for those attached to N and O atoms that are involved in the hydrogen bonding. Hydrogen bonds are denoted by dashed lines. The spheres marked with an asterisk (without H atoms attached to them) mark the O2A sites of two additional mol­ecules of fexofenadine hydrogen bonded to the carboxyl­ate groups of the central dimer.
