N2 - A discrete ammonium catechoiate hydrate of the composition NH4[C6H4(OH)2][C6H4(OH)O]·0.5H2O has been isolated and characterized by a single-crystal X-ray structure analysis. The crystals are monoclinic, space group C2/c (No. 15), Z = 8, a = 24.613(3), b = 8.706(1), c = 11.890(2) Å, β = 110.56(1)°. The crystal lattice features a network of hydrogen bonds, which clearly contribute significantly to the overall stability of the lattice. The water molecule is engaged as a donor and an acceptor in as many as four hydrogen bonds. Surprisingly, the crystalline compound is air-stable, while anhydrous ammonium catechoiate, as obtained by dissolving catechol in dry liquid ammonia, is quickly oxidized in air.
