合成一种由锯齿型水链连接的二维网状铜配合物{[Cu(pyc)2].H2O}n(pyc=2-Pyridineacid),并进行了结构表征。重复单元通过水簇链以氢键作用形成二维网状超分子层,层与层间借助吡啶环π-π堆积作用构筑成三维超分子结构。配合物为三斜晶系,空间群P-1,晶胞参数:a=5.123(5),b=7.634(7),c=9.208(8);α=74.697(12)°,β=84.453(12)°,γ=71.288(12)°;Z=1,R=0.0 798。
A two-dimensional network-like copper complex {[Cu (pyc) 2] .H2O} n (pyc = 2-Pyridineacid) was synthesized by sawtooth-shaped water chain and its structure was characterized. The repeating unit forms a two-dimensional network of supramolecular layers by hydrogen bonds, and the layer and the layer form a three-dimensional supramolecular structure by the π-π stacking effect of the pyridine ring. The complex is triclinic with a space group of P-1 with unit cell parameters of a = 5.123 (5), b = 7.634 (7), c = 9.208 (8); α = 74.697 (12) °, γ = 71.288 (12) °; Z = 1, R = 0.0798.
