N'-(2-Hydr-oxy-3,5-diiodo-benzyl-idene)-2-methoxy-benzohydrazide
Abstract:
The title compound, C(15)H(12)I(2)N(2)O(3), was synthesized by the condensation of equimolar amounts of 3,5-diiodo-salicylaldehyde and 2-methoxy-benzohydrazide in a methanol solution. There are two independent mol-ecules, A and B, in the asymmetric unit. The dihedral angle between the two benzene rings is 30.2 (2)° for mol-ecule A and 21.7 (2)° for mol-ecule B. There are intra-molecular O-H⋯N and N-H⋯O hydrogen bonds in each mol-ecule. The crystal studied was an inversion twin with a 0.59 (3):0.41 (3) domain ratio.
