摘要:
Eight lanthanide thiocyanate complexes of the type [Ln(NCS)(3)(PBH)(2)] and [Ln(NCS)(3)(MPB)(2)], where Ln = La, Pr, Nd, Sm, Eu, Gd, Dy and Y and PBH and MPB are 2-(2-pyriaylbenzimidazole) and 1-methyl-2-(2'-pyridyl)benzimidazole, respectively, have been synthesized and characterized by various physicochemical techniques such as conductance and thermogravimetric studies, electronic, IR, NMR (H-1 and C-13), EPR, CV and fluorescence spectral investigations. The nu(C=N) of the thiocyanate group indicates N coordination in all cases. (C) 1997 Elsevier Science Ltd.
