The title complex, [Ir(C15H9Br2O2)(C13H8NS)2], lies about a crystallographic twofold rotation axis passing through the IrIII atom and the central C atom of the bis­(bromo­phen­yl)propane-1,3-dionate ligand. The IrIII atom adopts a distorted octa­hedral geometry coordinated by two N atoms in the axial positions, and two C and two O atoms in the equatorial plane. The dihedral angle between the two thia­zole ring systems in the complex is 77.45 (10)°.

In the title compound (systematic name: {[(phenyl­formamido)­carbon­yl]amino}­methane­thio­amide), C9H9N3O2S, both benzoyl and terminal thio­urea fragments adopt transoid conformations with respect to the central carbonyl O atom. The benzoyl and thio­biuret groups are almost coplanar, making a dihedral angle of 4.40 (8)°. The mol­ecular structure is stabilized by two intra­molecular N—H...O hydrogen bonds. In the crystal, N—H...O and N—H...S hydrogen bonds link the mol­ecules into a tape running along [101].

The title compound, C9H9N3O2S, is a monoclinic (C2/c) polymorph of the previously reported triclinic structure [Kang (2013). Acta Cryst. E69, o1327]. The mol­ecule is almost planar with an r.m.s. deviation of 0.069 Å from the mean plane of all non-H atoms. The benzoyl and terminal thio­urea fragments adopt a transoid conformation with respect to the central carbonyl O atom. Two intra­molecular N—H...O hydrogen bonds are present. In the crystal, N—H...O and N—H...S inter­actions link the mol­ecules into zigzag chains extending along the c-axis direction.
