| Abstract: Some coordination compounds of rare earth elements (Ⅲ) with Trimethylamine N-oxide (TMAO), ［Ln(TMAO)3(NO3)］(NO3)2 and ［Ln(TMAO)6］(ClO4)3(Ln=La, Nd, Sm, Gd) have been prepared and characterized by elemental analysis, molar conductance, IR and Raman spectra. The stretch force on stants were calculated using GF matrix method. The results show that the strength of coordination bonds is increased with the atomic number. The molecular orbital of TMAO, La(TMAO)3(NO3)2+ and ［La(TMAO)6］3+ were calculated by semiempirecal INDO method. The results show that the N-O bond is stronger in coordination compounds than that in TMAO. |
