Pyridine-3-carboxamide–telluric acid (1/1)

Abstract

In the title structure, C6H6N2O·H6O6Te, the pyridine-3-carboxamide and telluric acid molecules are interconnected by conventional O—H...N, N—H...O and O—H...O hydrogen bonds of moderate strength as well as by π–π interactions between the pyridine rings. The strongest hydrogen bond in the structure is formed between a hydroxyl group of the H6TeO6 molecule and the N-pyrimidine N atom. The structure is unusual because of presence of the alternating sheets, which contain H6TeO6 and pyridine-3-carboxamide molecules, respectively. These sheets are aligned parallel to (001).
