摘要 以硝酸镉与吡啶-4-甲酸(HIA)为原料在水热条件下合成了配合物[Cd(IA)2(H2O)4],并用红外光谱、元素分析和X射线单晶衍射进行了表征。该配合物属三斜晶系,P-1空间群,晶胞参数为:a=6.4400(5)nm,b=6.9489(6)nm,c=9.4051(8)nm,α=95.2600(10)°,β=104.580(2)°,γ=111.570(2)°,V=0.037079(5)nm3。配合物中Cd(Ⅱ)位于变形八面体环境中,与分属于两个吡啶-4-甲酸根的2个N原子以及来自于四个配位水分子的O原子配位。 One new complex, [ Cd( IA) 2 ( H2 O) 4 ] ( HIA = isonicotinic acid) , was synthesized using the hy-drothermal reaction of Cd(NO3)2·2H2O with isonicotinic acid. The complex was characterized by elemental analysis and IR. Single crystal X-ray analysis revealed that the complex crystallized in the triclinic space group of P-1 with a=6. 4400(5) nm,b=6. 9489(6) nm,c=9. 4051(8) nm,α= 95. 2600(10)°, β=104. 580(2)°,γ=111. 570 (2)°,V = 0. 037079(5) nm3. The Cd(II) atom was coordinated by two N atoms from two different IA- ligands and four O atoms of H2 O, in a slightly distorted octahedral geometry.
