Four complexes, {[Ag(L)]NO3}(n) (1), {[Ag(L)(H2O)BF4}(n) (2), {[Ag-2(L)(3)](SbF6)(2)}(n) (3), {[Ag(L)]ClO4}(n) (4), were synthesized by treating chelating ligand trans-his (benzoylacetone)-1,4-diaminocyclohexane (L) with AgX (X=NO3-, BF4, SbF6-, ClO4-). The structures of these complexes were characterized by elemental analysis, infrared spectroscopy, and X-ray single-crystal diffraction. In the solid state, the ligands in the 2D networks of 1 and 2 exhibited two types of coordination modes: in 1, the CN bonds of the bridging ligand, 1,4-diaminocyclohexane, were axial, while in 2, the CN bonds were equatorial. On the other hand, the ligands in 3 exhibited two types of coordination modes, which formed only 1D complexes. Moreover, the ligands in 4 exhibited only one type of coordination mode, which formed a 2D network. Anions in 2,3 were not coordinated to Ag(I); However, 1 and 4 were coordinated to Ag (I). Meanwhile, the solid-state fluorescence of ligands and complexes was studied at room temperature. CCDC : 1061597, 1; 1061598, 2; 10615999, 3; 1061600, 4.
