Cover illustration: The compound trimesic acid-1,2-bis(1,2,4-triazol-4-yl)ethane-water (4/1/2) crystallizes in a layer structure where each sheet is composed of anellated hydrogen-bonded rings of six different sizes: R22(16), R33(18), R44(12), R44(18), R44(22) and R44(25). The two largest rings are associated with O-H...N bonds from the carboxyl groups to the triazole rings. However, the typical head-to-tail carboxyl-carboxyl R22(8) motif is not observed.
