本文制备了2-羰基丙酸(4-吡啶甲酸基)腙(H2PPFH)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).n[H2O(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=0.28。通过配合物的导电性能的测试, 发现它们都具有半导电性质。

Six transition metal complexes of 2-oxo-propionic acid (4-pyridinecarbonyl) hydrazone (H2PPFH) and the single crystal of a manganese complex have been prepared in this thesis. the structure and properties of these complexes were characterized by elemental analyses, IR and UV spectra, differential thermal analyses(DTA)and thermogravimetry (TG).A general formula for these complexes is M(PPFH).nH2O([M(II)=Mn.Fe, Co, Ni, Cu, Zn, n=0～2].The structure of the manganese complex was determined by X-ray single crystal diffraction analysis. the results whow that the crystal of the complex is monoclinic, of space group P21/n, with a=1.1252, b=0.9828, c=1.3708nm, β=66.03°, R=0.028. Besides , the electrical conductivities of six complexes were measured and their semiconductor-like behavior was discussed.
