以吡蚜酮为配体合成了单核的镍配合物[Ni(L)2(Ac)2(H2O)2]·4H2O(1)和双核的铜配合物[Cu2(L)2(Ac)4]·2H2O(2)(L=吡蚜酮),并对化合物进行了元素分析、红外、热重、X射线衍射、循环伏安等分析。X-射线单晶衍射仪分析表明:化合物1属于三斜晶系,P1空间群,镍离子采用六配位的变形八面体几何构型。化合物2属于单斜晶系,P21/c空间群,两个醋酸根桥连相邻的Cu(Ⅱ)离子形成了双核结构。电催化实验发现化合物1和2对H2O2具有明显的电催化活性。
A single-core nickel complex [Ni (L) 2 (Ac) 2 (H2O) 2] · 4H2O (1) and Cu2 (L) 2 (Ac) 4] · 2H2O (2) (L = pymetrozine). The compounds were characterized by elemental analysis, IR, TG, XRD and cyclic voltammetry. X-ray single crystal diffractometer analysis shows that: Compound 1 belongs to the triclinic system, P1 space group, and nickel ions adopt hexacoordinated deformed octahedral geometry. Compound 2 belongs to the monoclinic space group P21 / c, and the two acetate bridged the adjacent Cu (Ⅱ) ions to form a dinuclear structure. Electrocatalytic experiments showed that compounds 1 and 2 have obvious electrocatalytic activities for H2O2.
