Figure 9
Packing diagram for 3 (only major component shown) showing the complex three-dimensional array of hydrogen bonding involving R₂²(8), R₄⁴(12) and R₄⁴(20) rings propagating in the a-axis direction between the the 4-nitrophenyl group of one cation with the piperazinium ring of an adjacent cation (symmetry code: $[{1\over 2}]$ − x, $[{1\over 2}]$ − y, 1 − z, involving O1ⁱⁱⁱ and O2ⁱⁱⁱ; Table 4

), two cations and two anions in adjacent asymmetric units (−x, −y, 1 − z, involving O7ⁱ), and two cations and two anions in adjacent asymmetric units (symmetry code: − $[{1\over 2}]$ − x, $[{1\over 2}]$ + y, $[{1\over 2}]$ − z, involving O4^iv) .
