Figure 3
The interconnection of metal–carboxylate layers (which are orthogonal to the plane of the figure) by tr2ad ligands in (I), showing a set of O—H⋯O, O—H⋯N and C—H⋯O bonds. Note that hydrogen-bonded water molecules (O8) provide additional links between the hydroxide–copper clusters. Dashed lines indicate hydrogen bonding, O atoms are shaded gray, N and Cu atoms are shown as crossed circles, and methylene H atoms have been omitted for clarity.
