Figure 2
A packing diagram of compound (I), showing one N+—H⋯O− hydrogen-bonded (dashed lines) layer parallel to the (001) plane (see Comment). Atoms marked with an asterisk (*), hash (#) or dollar sign ($) are at the symmetry positions (x − , −y + , −z), (x, y + 1, z) and (x + , −y + , −z), respectively. |
