Figure 4
Part of the crystal structure of (II), showing the formation of the two-dimensional network built from R44(24) and R88(40) hydrogen-bonded rings. Hydrogen bonds are shown as dashed lines. For the sake of clarity, H atoms not involved in the motif have been omitted. [Symmetry codes: (i) x-1, y+1, z; (ii) -x+2, -y+2, -z; (iii) -x+1, -y+2, -z.] |
