Figure 2
The hydrogen-bonding assembly mode in (I), showing the fexofenadine dimer solvated by four molecules of methanol. The dimer consists of molecules related by inversion at (). Only the major disordered site (O2A) is shown. 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. [Symmetry code: (i) 1 − x, 1 − y, 2 − z.] |
