本文制备了2-羰基丙酸(4-吡啶甲酰基)腙(H_2PPFH)的六种过渡金属配合物和Mn(Ⅱ)配合物的单晶.通过元素分析、红外和紫外光谱、差热和热重分析对各配合物的结构和性质进行了表征.配合物的通式为M(PPFH)·nH_2O[M(Ⅱ)=Mn,Fe,Co,Ni,Cu,Zn,n=0～2].并通过X射线单晶衍射仪对Mn(Ⅱ)配合物的晶体结构进行了测定.分析表明该晶体属单斜晶系.空间群为P21/n,Z=4,a=1.1252,b=0.9828,c=1.3708nm,β=66.03°,R=0.028.通过对配合物的导电性能的测试,发现它们都具有半导体导电性质.
Six transition metal complexes of 2-oxopropionic acid (4-picolinoyl) hydrazone (H_2PPFH) and single crystal of Mn (Ⅱ) complexes were prepared by elemental analysis, IR and UV spectra, differential thermal and thermal The structures and properties of the complexes were characterized by means of reanalysis.The general formula of the complexes was M (PPFH) · nH 2 O [M (Ⅱ) = Mn, Fe, Co, Ni, Cu, Zn, n = 0 ~ 2] The crystal structure of Mn (Ⅱ) complex was determined by X-ray single crystal diffractometer.The results show that the crystal belongs to monoclinic system.The space group is P21 / n, Z = 4, a = 1.1252, b = 0.9828, c = 1.3708nm, β = 66.03 °, R = 0.028. By testing the conductivity of the complexes, they were all found to have semiconducting properties.
