摘要:

以邻苯二甲酸（H2phth）、乙酸锌或乙酸铜为原料，通过微波固相法合成邻苯二甲酸锌、铜配合物Zn(phth)?2H2O和Cu(phth)?H2O，用化学分析、元素分析、红外光谱、X射线粉末衍射、热分析等手段对配合物的组成和结构进行了表征。结果表明，邻苯二甲酸配体中的羧基以双齿桥式与Zn(Ⅱ)或Cu(Ⅱ)结合形成配合物，其热分解包括失水、配体的氧化分解过程，最后完全分解为金属氧化物。

Abstract:

Zinc(II) and copper(II) complexes of o-phthalic acid (H2phth) were synthesized by microwave solid-state method with o-phthalic acid, zinc acetate or copper acetate as raw materials. Chemical and element analysis, FT-IR, X-ray powder diffraction and TG-DTG analysis were applied to characterize the composition and structure of the compounds. The results show that the compositions of the complexes are Zn(phth)?2H2O and Cu(phth)?H2O, the ligand is coordinated simultaneity with Zn(II) or Cu(II) via the carboxyl group of o-phthalic acid to form bidentate chelates. Thermal decomposition processes of the complexes include dehydration, oxidation and pyrolysis of the ligand, and finally as metallic oxide.
