Preparation of Divalent Rare Earth Complexes with 3-Phenyl-5-(furyl-2)pyrazoline Dithioformate

Abstract

Abstract: The new solid complexes of divalent rare earth with 3-phenyl-5-(furyl-2)pyrazoline dithioformate RE(SSCNC₁₃HuNO)₂·xH₂O(RE= Sm, Eu, Yb, x=3,4) were prepared in Ar atmosphere.The composition and properties of the complexes as well as the differences between di- and trivalent rare earth complexes were studied on the basis of elemental analyses, IRspectra, electron spin resonance spectra, thermogravimetry, differential thermal analyses and the test for reducing property of the divalent rare earth complexes.

Key words: Divalent rare earth complexes, 3-Phenyl-5-(furyl-2)-pyrazoline dithioformate, Preparation, Properties
