Координационные соединения редкоземельных элементов с семикарбазоном салицилового альдегида

Abstract

Coordination compounds of rare earths with semicarbazone of salicylic aldehyde were synthesized. On the basis of data of element and X-ray phase analyses, IR spectroscopic, magnetochemical and thermogravimetric studies their composition was ascertained: Ln(HL)3•nH2O, Ln(HL)L•mH2O, (Ln = Y, La, Pr, Nd, Sm, Gd, Tb, Ho, Er, Yb; H2L = 2-НOC6H4CH=NNHC(O)NH2; n = 1, 2, 3; m = 2, 3, 4) and judgement on their structure was made
