Figure 5
A part of the crystal structure of compound (II)

, showing the formation of the R₂²(10) motif linking the (001) sheets. For the sake of clarity, the water molecules and H atoms bonded to C or N atoms which are not involved in the motif shown have been omitted. Atoms marked with an asterisk (*) are at the symmetry position (1 − x, 1 − y, 1 − z).
