合成了氢键连接的二维超分子配位化合物[Cu(mal)(tpm)(H2O)].2H2O(mal=丙二酸,tpm=三吡唑甲烷),并用元素分析和电子顺磁共振谱进行了表征。X射线单晶衍射表明该化合物的晶体属单斜晶系,Cc空间群,晶胞参数a=1.3624(2)nm,b=0.79318(14)nm,c=1.7526(3)nm,α=90°,β=102.352(3)°,γ=90°,V=1.8501(6)nm3,Z=4。中心Cu(Ⅱ)离子为五配位,处于扭曲的四方锥配位环境中。晶格水与配位水形成较强的氢键将配合物连接成二维超分子结构。
Hydrogen-bonded two-dimensional supramolecular complexes [Cu (mal) (tpm) (H2O)] 2H2O (mal = malonic acid, tpm = tris pyrazole methane) were synthesized and characterized by elemental analysis and electron paramagnetic resonance Spectra were characterized. X-ray single crystal diffraction showed that the crystal of the compound belongs to the monoclinic Cc space group with a = 1.3624 (2) nm, b = 0.79318 (14) nm, c = 1.7526 °, β = 102.352 (3) °, γ = 90 °, V = 1.8501 (6) nm3, Z = 4. The Cu (Ⅱ) ion in the center is a five-coordinate system and is in a distorted quadrangular pyramid coordination environment. Lattice water and coordination water to form strong hydrogen bonds to connect the complexes into two-dimensional supramolecular structure.
