4-(2,3-Dihydroxybenzyl­ideneamino)-3-methyl-1H-1,2,4-triazol-5(4H)-one

All the non-H atoms of the title compound, C(10)H(10)N(4)O(3), are almost coplanar, the maximum deviation from planarity being 0.065 (3) Å. The dihedral angle between the aromatic rings is 1.66 (6)°. The mol­ecule adopts the enol–imine tautomeric form with an intra­molecular hydrogen-bonding inter­a...

Sumario:All the non-H atoms of the title compound, C(10)H(10)N(4)O(3), are almost coplanar, the maximum deviation from planarity being 0.065 (3) Å. The dihedral angle between the aromatic rings is 1.66 (6)°. The mol­ecule adopts the enol–imine tautomeric form with an intra­molecular hydrogen-bonding inter­action between the Schiff base N atom and the hydr­oxy group. In the crystal, inter­molecular N—H⋯O and O—H⋯O hydrogen bonds link the mol­ecules into a three-dimensional network.
