Abstract:

In this paper, four silver(i) compounds, namely, {[Ag4(bipy) 4(chda)]·2NO3·10H2O}n (1), {[Ag2(bipy)2(chda)]·14H2O} n (2), {[Ag2(bipy)2(chda)] ·3EG·2H2O}n (3) and {[Ag2(bipy) 2(chda)]·H2chda}n (4) (where bipy = 4,4′-bipyridine, H2chda = trans-cyclohexane-dicarboxylate and EG = ethylene glycol), have been synthesized and characterized by single-crystal X-ray diffraction analyses. In all of these compounds, the Ag(i) centers are linked by bipy ligands to form 1D Ag(i)-bipy chain structures. The chda 2- anions of compound 1 adopt a μ4-coordination mode to connect the Ag(i)-bipy chains, forming a H-beam-like chain. In 2, the chda 2- anions adopt a μ2-coordination mode to connect the Ag(i)-bipy chains resulting in two distinct 2D brick wall-like layers. These layers are further stacked in an ABAB fashion through interlayer ππ stacking interactions giving rise to a 3D framework consisting of quasi-rectangular channels, in which an unusual double T5(2) water tape is trapped. For 3 and 4, the chda2- anions show a similar μ4-coordination mode to that of 1 and connect the Ag(i)-bipy chains to form 2D grid layers with identical compositions and connective topologies. The experimental studies show that the final structures are greatly influenced by the molar ratio of the components and the solvents, which can be rationally interpreted by the existence of various supramolecular interactions between the host and guest molecules within these compounds through a systematic structural comparison. Additionally, the thermal stability and luminescent properties of these compounds were also studied. © 2012 The Royal Society of Chemistry.
