N,N,N′,N′-tetramethylmamalonamide (TMMA) adducts of lanthanide chlorides and isothiocyanates

Abstract Lanthanide chloride and isothiocyanate adducts of tetramethylmalonamide of compositions LnCl 3 . 2TMMA (Ln = LaLu, Y, except Pm and Tm), Ln(NCS) 3 . 3TMMA (Ln = LaYb, Y, except Pm) and Lu(NCS) 3 . 2TMMA were obtained. The compounds were characterized by elemental analysis, i.r. spectra, conductance measurements and X-ray patterns.

Adducts between lanthanide nitrates and isothiocyanates with diphenyl-phosphinylmorpholide (DPPM)

Abstract The compounds obtained from the reaction between hydrated lanthanide nitrates, thiocyanates and diphenyl-phosphinyl-morpholide (DPPM) in ethanol are described. The adducts were characterized by elemental analysis and have the general formulas Ln(NO3)3. 3DPPM (Ln  LaLu, Y), Ln(NCS)3. 4DPPM (Ln  La, Ce, Pr, Nd) and Ln(NCS)3. 3DPPM (Ln  SmLu, Y). The i.r. spectra, molar conductances in nitromethane and nitrobenzene, and X-ray powder patterns of the compounds were determined.

Cyclic sulphoxides as ligands—II: Adducts between lanthanide nitrates and tetramethylene sulphoxide (TMSO)

Abstract The preparation of adducts between lanthanide nitrates and tetramethylene sulphoxide (TMSO) is described. Compounds corresponding to the compositions Ln(NO3)3. 4TMSO (LnLa, Ce), Ln(NO3)3. 3·5TMSO (LnPr, Nd, Sm, Eu) and Ln(NO3)3. 3TMSO (LnGd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Y) were obtained. The i.r. spectra, the visible spectra, the molar conductances in nitromethane and the X-ray powder patterns of the compounds were determined.
