經由金屬起始物AgX (X = NO3{, ClO4{和PF6{)及Ag2SO4與配位基2-Amino-4, 6-dimethylpyrimidine (adp)的反應,可獲得Ag(Ⅰ)的錯合物,其分子式如下: 化合物[Ag(NO3)(adp)]n,1 ; [Ag(ClO4)(adp).H2O]n,2 ; [Ag4(SO4)2(adp)2(H2O)4]n,3 和[Ag(PF6)(adp)2],4以上所有化合物的結構均已利用X-ray鑑定之。 化合物1-3為高分子,而化合物4則是一個單核金屬化合物。化合物1-2利用Ag及O原子分子間作用力以及C{H---O及N-H---O原子的氫鍵,使得分子間的連結形式構成螺旋狀的長鏈。化合物3中包含兩種形式之硫酸根離子鍵結模式,使得分子間的連結形式構成網狀的長鏈。化合物4是利用Ag及F原子分子間作用力以及C{H---F及N-H---F原子的氫鍵而形成的帶狀分子。
A series of silver (I) complexes of the types [Ag(NO3)(adp)]n,1; [Ag(ClO4)(adp).H2O]n, 2; [Ag4(SO4)2(adp)2(H2O)4]n, 3 and [Ag(PF6)(adp)2], 4 have been prepared by reactions of AgX (X = NO3{, ClO4{, PF6{) and Ag2SO4 with adp (adp = 2-Amino-4, 6-dimethylpyrimidine) in methanol solution. All the complexes have been structurally characterized by X-ray crystallography, FT-IR and 1H-NMR spectra. Complexes 1 - 3 are coordination polymers while complex 4 is mononuclear. Complexes 1 - 2 form helical chains which are interlinked through a series of Ag---O interactions and C-H---O and N-H---O hydrogen bondings. The SO42- anion in complex 3 shows both 2- bridging and 3- bridging bonding modes. In complex 4, the molecules are interlinked through extensive Ag---F, C-H---F and N-H---F interactions to form molecular bands.
