Dysprosium β-diketonate compounds have recently gained a lot of attention due to their intriguing multifunctional properties. In this paper, a series of “Dy(hfa)3•glyme” adducts have been prepared through a one-pot reaction, in dichloromethane, from dysprosium (III) acetate monohydrate, hexafluoroacetylacetone and glyme [Hhfa = 1,1,1,5,5,5-hexafluoroacetylacetone, glyme = bis-(2-methoxyethyl)ether, 2,5,8,11-tetraoxadodecane, 2,5,8,11,14-pentaoxapentadecane]. Based on the length of the polyether, various coordination frameworks have been obtained going from a mononuclear [Dy(hfa)3•diglyme] adduct, to a polymeric chain system for the [Dy(hfa)3•2H2O•triglyme], and an ionic structure for the [Dy(hfa)2•tetraglyme]+[Dy(hfa)4]. The relationship between the coordination framework in the “Dy(hfa)3•glyme” series and the magnetic and luminescent properties has been deeply investigated.

Abstract

Dysprosium β-diketonate compounds have recently gained a lot of attention due to their intriguing multifunctional properties. In this paper, a series of “Dy(hfa)3•glyme” adducts have been prepared through a one-pot reaction, in dichloromethane, from dysprosium (III) acetate monohydrate, hexafluoroacetylacetone and glyme [Hhfa = 1,1,1,5,5,5-hexafluoroacetylacetone, glyme = bis-(2-methoxyethyl)ether, 2,5,8,11-tetraoxadodecane, 2,5,8,11,14-pentaoxapentadecane]. Based on the length of the polyether, various coordination frameworks have been obtained going from a mononuclear [Dy(hfa)3•diglyme] adduct, to a polymeric chain system for the [Dy(hfa)3•2H2O•triglyme], and an ionic structure for the [Dy(hfa)2•tetraglyme]+[Dy(hfa)4]. The relationship between the coordination framework in the “Dy(hfa)3•glyme” series and the magnetic and luminescent properties has been deeply investigated.
