英文摘要 | 通讯作者地址: Huang, RB; Reaction of a flexible ligand 2,4-diamino-6-2-(2-methyl-1-imidazoly1) ethyl]-1,3,5-triazine (L) with Ag(I) in the presence of different counteranions afforded five complexes, namely, 2[Ag-n(L) (NH3)(n)].n[Ag-2(L)(2) (NH3)(2)].2n(nds) (1, H(2)nds = 1,5-naphthalenedisulfonic acid), 2[Ag-n(L)(n)].n[Ag-2(L)(2)(CF3CO2)(2)].nCF(3)CO(2) (2), [Ag-2(L)(2)(NH3)(2)].2(ClO4) (3), [Ag-2(L)(2)].2(NO3) (4), [Ag-2(L)(2)].2(ClO3) (5), which were characterized by element analysis, IR, PXRD and X-ray single-crystal diffraction. Structural analysis reveals that the L ligand take the same bidentate coordination mode in these complexes. The nds anion and the CF3CO2- anion lead to the coexistence of isomeric metallacycle and helical chain (ring-opening isomers) in the crystals of 1 and 2, while ClO4-,NO3-; and ClO3- anions afford dimeric metallacycles in complexes 3-5. Moreover, thermal gravity analysis (TGA) and emissive behaviors of these complexes were investigated.; National Natural Science Foundation of China 21071118 |
