A series of binuclear complexes with different molar ratio of europium to yttrium with cinnamic acid and o-phenanthroline were synthesized in anhydrous alcohol.
The enthalpies of solution in water of complexes of RE(NO3)3 (RE=La~Nd, Sm~Lu, Y) with L-α-Histidine (His) were measured at 298.15 K. The standard enthalpies of
