INVESTIGATION OF NEW POLYMER COMPLEXES BASED ON Yb(III) β-DIKETONATES
The metal polymers based on mono- and heteroligand β-diketonate complexes of Yb(III) with 2,7-dimethyl-octen-1-dione-3,5, 2,6-dimethyl-heptene-1-dione-3, 5 and with phenanthroline was synthesized. It has been defined that the coordination environment of the central ion remains unchanged during radic...
