以4-甲酰基-2,2,5,5-四甲基四氢呋喃-3-酮和间甲基苯胺为原料,经缩合反应制得配体(Z)-4-[(间甲苯胺基)亚甲基]-2,2,5,5-四甲基二氢呋喃-3(2H)-酮(L);以Cu(CH3 COO)2为铜源,L经配位反应合成了一个新型的铜(Ⅱ)配合物[Cu(L)2]n(Ⅰ),其结构经FT-IR,X-射线单晶衍射和元素分析表征.Ⅰ属单斜晶系,P2(1)/c空间群,晶胞参数a=11.361 3(19)(A),b=24.564(4)(A),c=12.026(2)(A),α=γ=90°,β=110.452(3)°,V=3 144.6(9)(A)3,Dc=1.226 g·cm-3,Z=4,R1=0.051 5,wR2 =0.113 2.
(Z)-4-((m-toluidino) methylene)-2,2,5,5-tetramethyl-dihydrofuran-3 (2H)-one (L) was prepared from 2,2,5,5-tetramethyl-4-oxo-tetrahydrofuran-3-carbaldehyde and m-toluidine by condensation reaction.A novel 3D supramolecular architecture [Cu(L)2]n(Ⅰ) was obtained through self-as-sembly of Cu(CH3COO)2 with L.The structure was characterized by FT-IR,single-crystal X-ray diffraction and elemental analysis.I belongs to monoclinic system,space group P2 (1)/c with a =11.3613(19) (A),b=24.564(4) (A),c =12.026(2) (A),a =γ =90 °,β=110.452(3)°,V=3 144.6(9) (A)3,Dc=1.226 g·cm-3,Z=4,R1 =0.051 5,wR2 =0.113 2.
