spectroscopy. In addition, a novel europium(+3) alkoxide Eu[OC(C4H3S)3]3(thf)3}·thf (15) was synthesized by the reaction between Eu[N(SiMe3)2]3 and the tertiary alcohol HO–C(C4H3S)3 (1) in thf. The molecular structure of this compound reveals an approximately octahedral coordination sphere around the europium(+3) metal centre with three methoxido ligands and three facially arranged tetrahydrofuran molecules
