Figure 3
A packing view of (I) along [100], orthogonal to the view in Fig. 2. The two-dimensional mesh structures are now seen in projection, as undulating chains (in bold) running horizontally (shown as flanking `A' labels). Regarding interplanar hydrogen bonds, only those not involving unbound anions or water solvent molecules are shown, linking planes along [010]. For clarity, coordinated bpp groups evolving upwards/downwards, unbound H2bpp cations, water solvent molecules and nonrelevant H atoms have been omitted. [Symmetry code: (i) x, y − 1, z.] |
