МОНО- ТА ЗМІШАНОЛІГАНДНІ КОМПЛЕКСИ Yb(III) З НОВИМИ β-ДИКЕТОНАМИ
New ytterbium (III) compounds with β-diketones (2,7-dimethyl-octene-1-dione-3,5 and 2,6-dimethylheptene-1-dione-3,5) and their derivatives with phenanthroline have been synthesized. The composition and chemical structure of the obtained complexes have been determined by several Physico-chemical inv...
