Figure 2 A part of the crystal structure of the title compound showing the asymmetric unit (expanded by symmetry to give complete organic cation and trimeric unit) and atom numbering. Displacement ellipsoids are drawn at the 50% probability level. Hydrogen bonds are represented by dashed lines·[Symmetry codes: (I) −x + 1, −y + 1, −z + 2; (II) −x + 2, −y + 2, −z + 1.] |
