Figure 1 Mol­ecular structure of (I), showing the atom-numbering scheme. Displacement ellipsoids are drawn at the 50% probability level. Inter-ion hydrogen bonds are shown as dashed lines, atoms marked with 'a′, 'b′ and 'c′ are at symmetry positions (−x, 2-y, 1-z), (1-x, 3-y, 1-z) and (−1 + x, −1 + y, z), respectively. An additional piperazine mol­ecule is shown to illustrate the hydrogen bonding.
