摘　　要：合成了一种新颖有机-无机杂化配位聚合物{[C_(12)H_(2)8N_(2)][(Pb_(3)I_(8))(DMF)_(2)]·2DMF}_(n),并进行了红外、紫外、热重表征,采用X射线衍射方法确定了晶体结构.结构解析表明,整个分子由阳离子(双质子化的N,N'-二丁基哌嗪)及聚阴离子链([(Pb_(3)I_(8))(DMF)_(2)]^(2-)_(n))组成,它们之间由静电作用结合在一起形成一维链状配位聚合物.依据晶体结构数据,采用-Gaussian03程序对产物进行量子化学计算.A novel organic-inorganic hybrid coordination polymer{[C_(12)H_(28)N_(2)][(Pb_(3)I_(8))(DMF)_(2)]·2DMF}_(n) was synthesized by self-assembling method and characterized by IR,UV/Vis and thermal analysis.The crystal structure was determined by X-ray diffraction analysis and its quantum chemical calculation was performed by Gaussian03 program.The title compound consists of cations([C_(12)H_(28)N_(2)]^(2+ )·)and anion chains([(Pb_(3)I_(8))(DMF)^(2-)_(2)]_(n))that are combined by static attractive forces in the crystal.
