摘要
酰胺型三足配体具有多配位点、半刚性结构、易合成和结构易变等特点,在与金属离子作用时.三条带配位原子的支链可绕中心形成孔径合适的空腔以选择性与不同的金属离子结合.进而有望组装形成各种新奇结构。目前.它们作为一类特殊结构的配位体而受到研究者的关注.在离子识别.
The title complex, [CuL][CuC12(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)^o, V=4.241 6(12) nm^3, Z=4, Dc=1.401 Mg·m^-3,μ= 1.189 mm^-1, F(000)=1880, 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. CCDC: 648900.
