چکیده
In the title compound, C(14)H(11)IN(2)O(3)·CH(4)O, the dihedral angle between the benzene rings is 33.2 (3)°. The mol-ecule displays trans and anti conformations about the C=N and N-N bonds, respectively. There is an intra-molecular O-H⋯N(azomethine) hydrogen bond. Inter-molecular N-H⋯O and O-H⋯O hydrogen bonds consolidate mol-ecules into a three-dimensional architecture.
