Abstract: In this paper, the benzoylhydrazine chelates of rare earth metal(Ⅲ) dodecahydrododecaborates have been synthesised by the reactions between LnCl3 and C(CH3)4N]2B12H12 in the presence of benzoylhydrazine (BH) in aqueous medium. These compounds have been examined by elemental analysis, IRspectra and electro-conductance measurements. They have the following formulae [Ln(BH)4]2 (B12H12)3 (Ln = La,Pr, Nd, Sm, Eu, Gd, Tb,Ho,Er,Tm,Yb).
