Syntheses and Properties of Benzoylhydrazine and Bu-tyrylhydrazine Complexes of Bivalent Transition Metal or ⅡB Group Metal Hydroborates 张伦 1 first-author 何东保 1 张开诚 1 张国敏 1 中南民族学院 中南民族学院 合成了26个闭式氧硼酸苯酰肼和丁酰肼合二价过渡金属和ⅡB族金属化合物。用元素分析和红外光谱方法鉴定了它们。化合物在室温空气中是稳定的。当阳离子相同时,化合物的热稳定性次序是:B 12 H 12 2- 化合物大于B 10 H 10 2- 化合物;阴离子相同时,热稳定性次序依金属离子而异:Mn 2+ < Fe 2+ < Co 2+ < Ni 2+ 和Zn 2+ > Cd 2+ > Hg 2+ ;金属离子和氧硼酸根均相同时,一般是丁酰肼络合物大于苯酰肼络合物。 26 compounds have been synthesized by the metathetical reaction between the benzoylhydrazine （BH） or butyrylhydrazine （BuH） chelates of bivalent transition metals or ⅡB group metal chlorides or sulfates and quaternary am-monium hydroborates in water-alcohol media. The products were identified by elemental analysis and IR spectra. These compounds except Fe 2+ containing complexes are stable in air at room temperature DTA results indicated that the order of the thermal stability of these compounds is as follows. 1) B 12 H 12- 2- > B 10 H 10- 2- containing compounds, 2)Ni 2+ > Co 2+ - > Fe 2+ - > Mn 2+ -and Zn 2+ - > Cd 2+ - > Hg 2+ - containing com-pounds, and 3) Bull- > BH- complexes. 1984-03-01 2021-04-01 3
