摘要
以硝酸锌和3,5-吡唑二羧酸(H3dcp)为原料在水热条件下合成了配合物[Zn(H2dcp)2(H2O)2]·(H2O)2,并用红外光谱、元素分析和X射线单晶衍射进行了表征。该配合物属单斜晶系,P21/c空间群,晶胞参数为:a=1.00567(9)nm,b=1.24627(11)nm,c=0.68635(2)nm,β=108.972(2)°,V=0.81350(10)nm3,Mr=447.62,Dc=1.827g/cm3,F(000)=456,Z=2。配合物中Zn离子与分属于两个吡唑二羧酸根的2个O原子、2个N原子以及来自于两个配位水分子的O原子配位。
A novel Zine（II） complex[Zn（H2dcp）2 （H2O）2 ]·（H20）2 was synthesized from the reaction of 3,5- pyrazoledicarboxylic acid and Zn（N03 ）2·6H2 0 by the hydrothermal method and characterized by elemental analysis, IR and X-ray single crystal structural analysis. It falls into the monoclinic and characteristic of the space group P21/c with a = 1.00567（9） nm, b = 1. 24627（ 11）nm, c = 0.68635（2）nm,β = 108. 972（2）°, V = 0. 81350（ 10）nm3, Mr = 447.62, Dc = 1. 827g/cm3 , F（000） = 456, Z = 2. The crystal structure shows that the zinc atom is coordinated with two 0 atoms and two N atoms of two H2dcpions and two 0 atoms from the coordinated water molecule.
