Characterization,luminescent properties,crystal structure determination,and thermal properties of [Tl(Ph2phen)Cl3(DMSO)]

The new mixed-ligand complex of [Tl(Ph₂phen)Cl₃(DMSO)] (1) is obtained from the reaction of TlCl₃?4H₂O with 4,7-diphenyl-1,10-phenanthroline (Ph₂phen) in a methanol solution. Suitable crystals of 1 are obtained for the X-ray diffraction measurement by methanol diffusion into a DMSO solution. This complex is characterized by spectral methods (IR, UV-Vis, ¹H NMR, and luminescence), elemental analysis, thermal analysis (TG, DTA), and single crystal X-ray diffraction.
