摘要:
In our continuous efforts to investigate the coordination architectures of silver(I) complexes with thioethers, we report herein the syntheses and crystal structures of three new silver(I) complexes, a trinuclear complex [Ag3L22(NO3)(2)](NO3)(CH3CN) 2 and two one-dimensional chain complexes [Ag2L1 (BF4)(2)(CH3CN)(2)](infinity) 1 and [Ag2L3 (NO3)(2)](infinity) 3, where L-1, L-2 and L-3 are three structurally related pyridyl dithioether ligands: 1,4-bis(2-pyridylthio)butane (L-1), 1,5-bis(2-pyridylthio)pentane (L-2) and 1,6-bis(2-pyridylthio)hexane (L-3). The structural differences of 1, 2 and 3 show the influences of the ligand spacers on the coordination modes of the terminal pyridylsulfanyl groups and the coordination geometries of the Ag-I ion. There exist (AgAg)-Ag-... contacts in the three complexes, C-(HF)-F-... weak hydrogen bonds in 1, (AgS)-S-... weak coordination bonds in 2 and (AgO)-O-... weak interactions in 2 and 3, and these weak interactions link the low-dimensional complexes into high-dimensional supramolecular structures and further stabilize the crystal structures in the solid states.
