Abstract
Stable complex compounds ef dimethyl sulfoxide(DMSO) with lanthanoid perchlorates of the formura M(CIO)3, nDMSO (M=La, Ce, Pr, Nd, Sm, Eu, Gd and Tb, n ns 8; M=Dy, Ho, Er, Tm, Yb and Lu, n s 7) have been prepared, and their infra-red spectra in the 4000-v200 cmm-i region were measured. The spectral evidences suggested that coordination of DMSO occurred with its oxygen atom for all lanthanoid metals. The frequencies and intensities of v(M-O)were found to depend on the ionic radii of the lanthanoid. On the basis of the results obtained it was concluded that the strength of M-O bond increased with decreasing ionic radii, and these co plexes contained both seven-and eight ordination compounds.
