摘要

利用過渡金屬鹽類CuCl和CuBr與配位基2-胺基-5-鹵素嘧啶配位基pymX (X = I, Br, Cl) ，分別與HCl以及HBr水溶液反應，可得到{[CuCl2(HpymI)] • H2O}n, 1，{[CuBr2(HpymI)] • H2O}n, 2，{[CuCl2(HpymBr)] • H2O}n, 3，{[CuBr2(HpymBr)] • H2O}n, 4 和 {[CuCl2(HpymCl)] • H2O}n, 5 。化合物[(HpymCl)CuBr3(HpymCl)], 6, 為利用CuBr 與pymCl在甲醇溶液中再加入HBr反應而得到，以上這些結構已經利用X-ray鑑定。

化合物1 - 5 為利用鹵素進行橋接的鋸齒鏈化合物，再利用X---X的鹵素作用力以及N-H---X，N-H---O以及O-H---X氫鍵作用力形成超分子結構。而化合物6則是單核的金屬錯化合物，再利用N-H---Br以及C-H---Br氫鍵作用力形成超分子鏈。而這些超分子鏈則利用Br---Cl 鹵素作用力以及C-H---Br氫鍵作用力連接並形成3-D的超分子結構。

A series of copper(I) complexes {[CuCl2(HpymI)] • H2O}n (pymI = 2-Aimo-5-iodopyrimidine), 1, {[CuBr2(HpymI)] • H2O}n, 2 , {[CuCl2(HpymBr)] • H2O}n (pymBr = 2-Aimo-5-boropyrimidine), 3, {[CuBr2(HpymBr)] • H2O}n, 4, and {[CuCl2(HpymCl)] • H2O}n (pymCl = 2-Aimo-5-choropyrimidine), 5 have been prepared by the reactions of CuCl and CuBr with 2-Amino-5-halopyrimidine in solution of HCl and HBr, respectively. [(HpymCl)CuBr3(HpymCl)], 6, was prepared by the reaction of CuBr and pymCl in solution of HBr. These complexes have been structurally characterized by X-ray crystallography.
In complexes 1 - 5, the zigzag chains are interacted through X---X (X = Cl, Br, I) interaction and N-H---X, N-H---O and O-H---X hydrogen bonds. Complex 6 is mononuclear, and the molecules are interacted through Br---Cl interaction, C-H---Br and C-H---Br hydrogen bonds.
