Abstract

The temperature dependences of the molar magnetic susceptibility of luminescent europium compounds with cinnamic acid [Eu(Cin)3] n and Eu(Cin)3 · 2D · H2O (where Cin is the cinnamic acid anion and D is phen (1,10-phenanthroline) or dipy (2,2-dipyridyl)) were studied at temperatures from 300 to 2 K. The molar magnetic susceptibility of the compounds increased in the series Eu(Cin)3 · 2dipy · H2O < Eu(Cin)3 · 2phen · H2O < [Eu(Cin)3] n . The energy distances λlum between the 7 F 0 ground level and the 7 F 1 state in the luminescence spectra correlated well with λmagn obtained from magnetochemical data.
