The asymmetric unit of the title compound, [InCl3(C12H12N2)(C3H7NO)]·0.5H2O, contains two independent InIII complex mol­ecules with similar structures and one lattice water mol­ecule. In each complex mol­ecule, the InIII atom is six-coordinated in a distorted octa­hedral geometry, formed by two N atoms from the chelating 5,5′-dimethyl-2,2′-bipyridine ligand, one O atom from a dimethyl­formamide and three facial Cl atoms. In the crystal, the lattice water mol­ecule is linked to the complex mol­ecules via O—H...Cl hydrogen bonds. Further weak C—H...Cl and C—H...O hydrogen bonds result in the formation of a three-dimensional structure.

The title compound, [Cd2Br4(C24H16N2)2], consists of a centrosymmetric dimeric unit in which two Br atoms bridge two CdII atoms, forming a four-membered ring. A terminal Br atom and a bidentate chelating 4,7-diphenyl-1,10-phenanthroline ligand complete a square-pyramidal geometry for the CdII atom. In the crystal, C—H...Br hydrogen bonds and π–π contacts between the pyridine and phenyl rings [centroid–centroid distances = 3.704 (4) and 3.715 (4) Å] lead to a three-dimensional supra­molecular structure.
