Slow co-crystallization of a solution of benzene-1,3,5-tri-carb-oxy-lic acid with a large excess of 4-hy-droxy-pyridine produces an inter-penetrating, three-dimensional, hydrogen-bonded framework consisting of three 4-pyridone and one benzene-1,3,5-tri-carb-oxy-lic acid mol-ecules, C9H6O6·3C5H5NO. This structure represents an ortho-rhom-bic polymorph of the(More)
The structure of the title salt, C5H6NO(+)·C9H5O6 (-), (I), shows that 4-hy-droxy-pyridine has abstracted an H atom from benzene-1,3,5-tri-carb-oxy-lic acid, yielding a pyridinium cation and carboxyl-ate anion. The two ions form an extensive three-dimensional hydrogen-bonded network throughout the crystal. The hydrogen bonds that comprise the core of the(More)
