Figure 2
A fragment of the structure of (I), showing the formation of a square network via O—H⋯N hydrogen bonding and slipped π–π stacking between the metal–organic cations. C-bound H atoms have been omitted for clarity, N atoms are shaded grey and dashed lines indicate hydrogen bonding. [Symmetry code: (iv) x + 1, y − 1, z; (v) −x + 2, −y, −z + 1.] |
