以2-甲基-5-羧基吡嗪为配体合成了1个三维超分子配合物Cu(2-mpac)Cl(H2O).H2O(1)(2-mpac:2-甲基-5-羧基吡嗪),并利用元素分析、IR、X-射线单晶衍射及热重分析等手段对配合物(1)进行了结构表征.结果表明:配合物(1)属于三斜晶系,P-1空间群,P-1,a=3.8306(6),b=11.395 7(18),c=11.5596(18),α=111.321(2)°,β=96.282(2)°,γ=98.667(2)°,V=457.25(12)°3,Z=2,S=1.019,,最终残差因子(I>2σ(I))R1=0.0375,wR2=0.0945,对于全部数据R1=0.0423,wR2=0.0991.
A 3-dimensional supramolecular complex Cu (2-mpac) Cl (H2O) was synthesized by using 2-methyl-5-carboxypyrazine as a ligand.H 2 O (1) was characterized by means of elemental analysis, IR, X-ray single crystal diffraction and thermogravimetric analysis.The results showed that the complex (1) belongs to triclinic system and P -1 space group, a = 3.8306 (6) , b = 11.395 7 (18) , c = 11.5596 18, α = 111.321 (2) °, β = 96.282 (2) °, R1 = 0.0375, wR2 = 0.0945 for the final residual factor (I> 2σ (I)) for the entire data with γ = 98.667 (2) ° and V = 457.25 (12) ° ,3, Z = R1 = 0.0423, wR2 = 0.0991.
