二乙酰丙酮桥联双核锌（Ⅱ）配合物的合成与热谱分析

摘要

A novel bis（β-diketonato）-bridged di-zinc（II） complex,[Zn2（C10H12O4）（C15H11O2）2]·H2O（C15H11O2=1,3-diphenylpropane-1,3-dione anion;C10H12O4 =bisacetylacetonate dianion）,was synthesized and characterized by the element analysis,conductivity,infrared spectra,electronic spectra and ESI-MS.The thermal properties of compound were studied by TG-DSC methods in an atmosphere of N2.From 37~152℃,a mass loss of 2.41% is observed.From 152~512℃,a mass loss 0f 50.84% is observed.The max peaks at 55℃ and 323℃ in DTG are observed by exothermic decomposed reaction,respectively.%以高氯酸锌、二苯甲酰甲烷、二乙酰丙酮为原料合成了新型固态三元配合物[Zn2（C10 H12 O4）（C15H11O2）2].H2O,经元素分析、电导率、红外光谱、电子光谱和电喷雾质谱等手段表征,确定了配合物的组成。用热重-差示扫描量热分析法（TG-DSC）对其进行了热分析研究,在37～152℃之间质量损失约2.41%,152～512℃之间质量损失约50.84%,在55℃、323℃分别有两个最快失重温度点。
