Abstract

In the title mol­ecule, C8H8IN3O2, there is an intra­molecular O—H⋯N hydrogen bond between the hy­droxy group and the imine N atom, which generates an S(6) ring. In the crystal, the carbonyl O atom accepts two different N—H⋯O hydrogen bonds, which connect mol­ecules with two R22(8) motifs.
