4-(2,3-Dihydroxybenzyl-ideneamino)-3-methyl-1H-1,2,4-triazol-5(4H)-one.

ABSTRACT: 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 mol-ecule adopts the enol-imine tautomeric form with an intra-molecular hydrogen-bonding inter-action between the Schiff base N atom and the hydr-oxy group. In the crystal, inter-molecular N-H?O and O-H?O hydrogen bonds link the mol-ecules into a three-dimensional network.

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 mol-ecule adopts the enol-imine tautomeric form with an intra-molecular hydrogen-bonding inter-action between the Schiff base N atom and the hydr-oxy group. In the crystal, inter-molecular N-H⋯O and O-H⋯O hydrogen bonds link the mol-ecules into a three-dimensional network. ...[more]
