【Abstract】 The title complex, [CuL][CuCl2(NO3)2] [L=N,N,N′,N′,N″,N″-Hexaisopropyl-2, 2′, 2″-Nitrilotris(2,1-ethoxy)triacetamide], has been synthesized by using an amide-type tripodal ligand with Cu(NO3)2 and then characterized by X-ray single crystal structure analysis. It belongs to monoclinic, space group P21/c with a= 1.522 7(2) nm, b=1.277 8(2) nm, c=2.184 5(4) nm, β=93.680(10)°, V=4.241 6(12) nm3, Z=4, Dc=1.401 Mg·m-3, μ=1.189 mm-1, F(000)=1 880, and final R1=0.050 9, wR2=0.125 3. The results show a Cu(Ⅱ) ion was encapsulated by the three chains of the cup-like heptadentate ligand and four-coordinated by the central nitrogen atom and three oxygen atoms from the ligand.
