摘要: 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。 |

Abstract: Two complexes of Ni(Ⅱ) and Cu(Ⅱ) with pymetrozine ligands, namely [Ni(L)2(Ac)2(H2O)2]·4H2O (1) and [Cu2(L)2(Ac)4]·2H2O (2) (L=pymetrozine) have been prepared and characterized by elemental analysis, powder X-ray diffraction (XRD), thermal analysis (TG), IR, and cyclic voltammetry (CV). X-ray single-crystal structural analysis revealed that 1 was a mononuclear structure, and the Ni(Ⅱ) ion adopted a distorted octahedral coordinated geometry formed by two nitrogen atoms from pymetrozine ligands, two oxygen atoms from coordinate H2O and the other two oxygen atoms from acetates. Complex 2 was a binuclear structure, in which a pair of acetates anions bridged two Cu(Ⅱ) cations to form a dinuclear molecule. CV analyses showed that compounds1 and 2 had electrocatalytic activities towards H2O2. CCDC: 964347, 1; 964348, 2. |
