Figure 2
(a) The molecular structure of (II), showing the atom-labelling scheme. Displacement ellipsoids are shown at the 50% probability level and H atoms as spheres of arbitrary radii. Dashed lines indicate hydrogen bonds. (b) A view of the hydrogen-bonded three-dimensional network in (II). H atoms bonded to C atoms have been omitted for clarity. (c) The O—H⋯O hydrogen-bonded two-dimensional layer of malate anions, showing the binary graph set motif R44(22). [Symmetry codes: (i) , , ; (ii) 1 + x, y, z.] |
