STUDIES ON SOLID STATE REACTIONS OF COORDINATION COMPOUNDS L Ⅳ.SYNTHESIS OF SCHIFF BASE COMPLEXES WITH Co(Ⅱ), Ni(Ⅱ)AND Cu(Ⅱ) BY ONE STEP SOLID STATE REACTIONS AT LOW HEATING TEMPERATURES

本文研究了Co(Ac)_2·4H_2O,Ni(Ac)_2·4H_2O,Ca(Ac)_2·H_2O与5个有代表性Schiff碱的低热(<70℃)固相化学反应。通过上述固相反应合成了9个钴、镍、铜的Schiff碱配合物。经元素分析、红外光谱、XRD,DTA等测定,确定了固相合成产物组成。讨论了配体的结构及Co(Ac)_2·4H_2O、Ni(Ac)_2·4H_2O、Cu(Ac)_2·H_2O晶体结构的稳定性对固相反应的影响。

Nine Schiff base complexes of Co(Ⅱ),Ni(Ⅱ)and Cu(Ⅱ)have been synthesized by onestep solid state reactions at room temperature to 70℃. The results of elemental analysis, IR, XRD, and DTA show that the products synthesized are pure compounds. The effects of structure of both Schiff base and metal acetate on the solid state reaction are discussed.
