[In(5,5’-DiMeBiPy)Cl₃(DMSO)].2(DMSO) complex (5,5’-DiMeBiPy is 5,5’-Dimethyl-2,2’-bipyridine) was prepared from reaction of InCl₃.4H₂O with 5,5’-DiMeBiPy in 1.1 molar ratio in DMSO. This compound has been characterized by IR, ¹H NMR, UV-Vis spectroscopy as well as X-ray crystallography. This compound crystallizes in the space group Pī of the triclinic system. The unit cell dimensions is: a = 8.6695(8) Å, b = 12.8456(14) Å, c = 13.0877(12) Å, a = 78.258(8)º, β = 85.270(8)º, g = 74.932(8)º. According to X-ray structure determination, there are one molecules of the complex and two DMSO solvent molecules in the asymmetric unit. In this complex the geometry at the indium (III) center is octahedral, formed by two nitrogen atom of 5,5’-DiMeBiPy ligand, three chloride ions and one DMSO molecule in trans position to chloride ion.
