摘要: 本文合成了一系列十二氢十二硼酸苯酰肼合稀土金属(Ⅲ)螯合物,对它们进行了元素分析、红外光谱测定和摩尔电导率的测量,确定化合物的分子式为[Ln(BH)4]2(B12H12)3(BH=苯酰肼),通过DTA法测定了化合物的热稳定性。

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).
