A mononuclear Co complex, [Co(H2dapsc)(H2O)Cl]Cl·2H2O (1), with a pentagonal bipyramidal configuration was obtained by reflux reaction of CoCl2·6H2O and 2, 6-diacetylpyridine-bis(semicarbazone) (H2dapsc) in a mixed solvent of water and ethanol. The neutral ligand H2dapsc molecule provides five coordination atoms to form the equatorial plane of 1, while a water molecule and a Cl- ion occupy their axial positions. At the same time, the solid structure contains a valence counteranion Cl- ion and two lattice water molecules. The study of DC magnetic susceptibility indicates that complex 1 has strong magnetic anisotropy. The AC magnetic properties show the existence of slow magnetic relaxation behavior, which is dominated by both direct and Raman processes. The energy barrier for magnetization reversal was 55.55 K. Based on theoretical calculations, it can be concluded that the main reason for the slow magnetic relaxation behavior is the rhombic anisotropy of the pentagonal bipyramidal structure. The calculated D and E values were 45.68 and-0.32 cm-1.

采用浸渍吸附法,以多孔碳纳米笼(CNC)作为载体,简便构建了单原子铂/CNC (SA-Pt/CNC)纳米酶。通过透射电子显微镜(TEM)、高分辨透射电子显微镜(HRTEM)和X射线光电子能谱(XPS)深入解析了SA-Pt/CNC的微观结构。酶活性测试表明,SA-Pt/CNC表现出优异的类过氧化物酶活性,能高效催化过氧化氢氧化各种底物分子。
