چکیده
The title compound, 4C(9)H(6)O(6)·C(6)H(8)N(6)·2H(2)O, crystallizes in a layer structure where each sheet is composed of anellated hydrogen-bonded rings of six distinct sizes: R(2) (2)(16), R(3) (3)(18), R(4) (4)(12), R(4) (4)(18), R(4) (4)(22) and R(4) (4)(25). The two largest rings, viz. R(4) (4)(22) and R(4) (4)(25), are associated with O-H⋯N bonds from the carboxyl groups to the triazole rings. The typical head-to-tail carbox-yl-carboxyl R(2) (2)(8) motif is not observed.
