Figure 5
Part of the crystal packing for (II), showing the N—H⋯O and O—H⋯O hydrogen-bonded (dashed lines) networks, highlighting the association of malate ions via R22(10) and R44(20) ring formation along the c axis. H atoms not involved in hydrogen bonding have been omitted for clarity. [Symmetry codes: (i) x − 1, y, z; (ii) x, y + 1, z; (iii) x + 1, y, z; (iv) −x + 1, −y, −z + 2.] |
