Synthesis, Crystal Structure Of Coordination Compounds Of Triazolyl Ligand With Silver (Ⅰ)

In this thesis, we synthesized seven ligands (two of them are new triazoles) and seven silver complexes which are characterized by element analyses, IR spectra, 1HNMR. In addition, the five coordination compound were structurally characterized by single crystal X-ray diffraction.The seven ligands are 3,5-(4'-EtPh)2tzH 4-NH2-3,5-Ch2-tzH 3,5-Ch2-tzH 4-NH2-3,5-dip-tbuph-1,2,4-triazole 4-NH2-3,5-nBu2-tzH 4-NH2-3,5-1Bu2-tzHThe seven complexes are: Ag2(4-NH2-3,5-Ch2-tz)2(NO3)2(1) Ag4(4-NH2-3,5-Ch2-tz)4(ClO4)4(2) Ag (4-NH2-3,5-Ch2-tz)3(ClO4)4 (3) Ag4(4-NH2-3,5-nBu2-tz)6(ClO4)4(4) Ag3(4-NH2-3,5-1Bu2-tz)6(CF3SO3)3(5) [Ag5.5(3,5-(4'-EtPh)2tz)4(NO3)1.5]n(6) Ag4(4-NH2-p-tbuph-tz)6(ClO4)8 (7)The complexes are divided into five types based on structural study: 1. Mononuclear complex:Ag (4-NH2-3,5-Ch2-tz)3(ClO4)4(3) 2. Dinuclear complex:Ag2(4-NH2-3,5-Ch2-tz)2(NO3)2 (1) 3. Trinuclear complexes:Ag3(4-NH2-3,5-1Bu2-tz)6(CF3SO3)3 (5) 4. Tetranuclear complexes:Ag4(4-NH2-3,5-Ch2-tz)4(ClO4)4 (2),Ag4(4-NH2-3,5-nBu2-tz)6(ClO4)4 (4) and Ag4(4-NH2-p-tbuph-tz)6(C104)8 (7) 5.3-D Polymer:[Ag5.5(3,5-(4'-EtPh)2tz)4(NO3)1.5]n (6) Based on the results of our study, we draw the following conclusions:(1). The substitutes at 3,5-position of triazole is one of the important deteminants to dicate the structure of Ag(Ⅰ)-triazole complexs. Different structures will be obtained when change the shape and the size of the substitute groups.(2). Anion have huge influence on the structure of Ag(Ⅰ)-triazole. Different structures will be obtained when different anions are used. (3). The substitutes at 4-position of triazole have certain influence on the structure of Ag(I)-triazole complexs.
