Indium(III) complexes containing bithiazole derivatives, chloride, methanol, and dimethyl sulfoxide: Xray studies, spectroscopic characterization, and thermal analyses

چکیده مقاله

[In(dm4bt)Cl ₃(MeOH)]·0.5dm4bt (1) (dm4bt is 2,2′dimethyl4,4′bithiazole) and [In(4bt)Cl ₃(MeOH)] (2) (4bt is 4,4′bithiazole) were prepared from the reaction of 4,4′bithiazole and 2,2′dimethyl4,4′bithiazole with InCl ₃·4H ₂O in methanol, respectively. [In(4bt)Cl ₃(DMSO)] (3) was also prepared from recrystallization of 2 in DMSO. These complexes were characterized by IR, UVVis, ¹H NMR, ¹³C{ ¹H} NMR, and luminescence spectroscopy and their structures were studied by singlecrystal Xray crystallography. The thermal stabilities of 1 and 3 were studied by thermogravimetric and differential thermal analyses. Copyright © 2012 Taylor and Francis Group, LLC.
