4-Amino-5-(2-hydroxy­benzyl­idene­amino)benzene-1,2-dicarbonitrile

A new tetra­dentate unsymmetrical Schiff base, C(15)H(10)N(4)O, has been synthesized from 4,5-dicyano-o-phenyl­enediamine and o-vanillin in refluxing ethanol. The dihedral angle between the two benzene rings is 39.0 (1)°. There are intra­molecular O—H⋯N and weak inter­molecular N—H⋯O and N—H⋯N inter...

Sumario:A new tetra­dentate unsymmetrical Schiff base, C(15)H(10)N(4)O, has been synthesized from 4,5-dicyano-o-phenyl­enediamine and o-vanillin in refluxing ethanol. The dihedral angle between the two benzene rings is 39.0 (1)°. There are intra­molecular O—H⋯N and weak inter­molecular N—H⋯O and N—H⋯N inter­actions.
