1. Compostos de adição entre iodetos de itrio e lantanídeos(III) e a N,N,N\ ,N\ - tetrametilmalonamida / N, N, N\ , N\ - tetramethylmalonamide adducts of lanthanide iodides
Addition compounds of formula Lni3.xTMMA (x = 5 for Ln = La, Ce and x = 4 for Ln = Pr - Lu, Y) were prepared by reaction of N,N.N\ ,N\ -tetramethylmalonamide (TMMA) and lanthanide iodides in acetone. The crystalline adducts present the same, but fainter colors of the corresponding lanthanide ions; they are in general practically not hygroscopic and melt with
