Synthesis,structure and properties of Schiff base copper mononuclear complex

合成了一个铜单核配合物Cu(HL)2(H2L=(水杨酸乙酯缩水合肼)缩2-吡啶甲醛),利用红外光谱,紫外-可见光谱和X射线单晶衍射对这个配合物的结构和性质进行了表征.结果表明,该配合物属正交晶系,Aba2空间群,晶胞参数为a=1.292 0(2)nm,b=1.806 0(3)nm,c=1.092 4(2)nm,α=β=γ=90°,V=2.549 0(7)nm3,Z=4,Dc=1.418g·cm-3,μ=0.901 mm-1,F(000)=1 116,R1=0.074 9,wR2=0.164 9.配合物的结构是两个配体夹着一个金属铜原子的十字交叉结构.

A copper mononuclear complex Cu（HL ）2 ,where H2 L denotes the （ethyl salicylate shrink hydrazine hydrate） shrink 2‐pyridyl formaldehyde ,has been synthesized and its struc‐ture and properties were determined by infrared spectra ,UV‐Vis spectra and X‐ray single crys‐tal diffraction .Results indicate that this compound belongs to orthorhombic system ,and the space group is Aba2 with lattice parameters a = 1 .292 0（2） nm ,b = 1 .806 0（3） nm ,c =1 .092 4（2） nm ,α = β = γ = 90＆#176; ,V = 2 .549 0（7） nm3 ,Z = 4 ,D c = 1 .418 g ？cm- 3 ,μ =0 .901 mm- 1 , F（000） = 1 116 , R1 = 0 .074 9 , wR2 = 0 .164 9 .The structure of complex is that a copper atom is sandwiched of two ligand molecules in crossing directions .
