Abstract

The exchange reaction of anhydrous YbCl3 with [1,3-C6H4{NC(Ph)N(SiMe3)}2Li2(THF)2]2 (I) (4 : 3 molar ratio, THF) gave ansa-bis(amidinate) ytterbium complex [1,3-C6H4{NC(Ph)N(SiMe3)}2]3Yb2 (II) in which three bis(amidinate) ligands form µ-bridges between two Yb3+ ions. An X-ray diffraction study (CIF file CCDC no. 1964848) showed that the dimeric structure of II is formed upon simultaneous coordination of κ2-N,N-chelating moieties of three ligands to two ytterbium atoms.
