摘要
The title compound, C(15)H(12)I(2)N(2)O(3), was synthesized by the condensation of equimolar amounts of 3,5-diiodosalicylaldehyde and 2-methoxybenzohydrazide in a methanol solution. There are two independent molecules, A and B, in the asymmetric unit. The dihedral angle between the two benzene rings is 30.2 (2)degrees for molecule A and 21.7 (2)degrees for molecule B. There are intramolecular O-H center dot center dot center dot N and N-H center dot center dot center dot O hydrogen bonds in each molecule. The crystal studied was an inversion twin with a 0.59 (3): 0.41 (3) domain ratio.
