| Abstract: Three kinds of lanthanide compounds of 3-sulfo-4-hydroxycoumarin(H2SHC) with compositions Ln(HSHC)3·9H2O (Ln=La、Pr、Nd、Gd、Dy、Er、Yb、Y),Ln2(SHC)3·nH2O(Ln=La、Pr、Nd、Sm、Gd,n=4 or 6) and Na3Ln(SHC)3·H2O (Ln=Er,Yb),have been synthesized and characterized by elemental analysis,TGA,molar conductance,IR and electronic absorption spectra.On the basis of experimental results,we suggest the probable structure (l)and(2) for Ln(HSHC)3·9H2O、(4) for Ln2(SHC)3·nH2O,and(5)for Na3Ln(SHC)3· H2O.The results of IR and electronicabsorption indicate the occurrence of some valent character between SHC2- and Ln3+ in Ln2(SHC)3·nH2O and Na3Ln(SHC)3·H2O.The shapes and oscillator strengths ofhypersensitive transition of Er3+ and Nd3+ compounds are studied. |
