Figure 5
Partial view of the packing in 1, showing hydrogen bonds within the hydrophilic chain (red dashed lines) and non-classical C—H⋯O hydrogen bonds (blue dashed lines) between methylene H atoms of the cations and oxygen atoms of the orotate anions. [Symmetry codes: (i) −x + 1, −y + 1, −z + 1; (iii) x + 1, y, z; (iv): x + 1, −y + $[{3\over 2}]$ , z − $[{1\over 2}]$ ; (v) x, −y + $[{3\over 2}]$ , z − $[{1\over 2}]$ .] Butyl-group H atoms not involved in hydrogen bonds have been omitted. The minor congener of the terminal methyl group has been omitted.
