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.
