摘　　要：以1,2,5-噻二唑-3,4-二甲酸(H_2tdzdc)为主配体,卡角型2-(5-(对甲苯基)-1H-1,2,4-三唑-3-)吡啶(Http)为辅助配体,与氯化锰在水热条件下反应合成一例锰(Ⅱ)配合物。通过单晶X-射线衍射确定配合物的结构,并对其进行元素分析、红外光谱表征。单晶结构解析表明:配合物[Mn_2(tdzdc)_2(Http)_4]为零维双核簇结构,属于P2_1空间群,单斜晶系。配合物为分成两叶的中心对称的二核簇,每一叶中包括一个中心Mn(Ⅱ)离子,一个tdzdc~(2-)和两个Http配体,且两个Http分别采用了不同的配位构型。In this paper,1,2,5-thiadiazole-3,4-dicarboxylic acid(H 2tdzdc)was used as the main ligand and cargotype 2-(5-(p-tolyl)-1h-1,2,4-triazole-3-)pyridine(Http)was used as the auxiliary ligand to synthesize a manganese(II)complex with manganese chloride under hydrothermal conditions.The structure of the complex was determined by single crystal X-ray diffraction.Elemental analysis and infrared spectrum characterization were performed.The analysis of single crystal structure shows that the complex[Mn 2(tdzdc)2(Http)4]is a zero-dimensional binuclear cluster structure,belonging to P 21 space group,monoclinic crystal system.The complexes are centrosymmetric binuclear clusters divided into two lobes,each of which includes a central Mn(II)ion,a tdzdc 2-,and two Http ligands with different coordination configurations.
