Figure 2
Hydrogen-bonding modes of (a) the maH+ cations, (b) the HL− anions and (c) the water molecules in (I). Hydrogen-bond interactions are represented by dashed lines. [Symmetry codes: (vii) x + 1, y, z; (viii) x − 1, y − 1, z; for other symmetry codes, see Table 2.] (In the electronic version of the paper, P, C, N, O and H atoms are drawn as purple, black, blue, red and green spheres, respectively.) |
