A set of Ag-based metal coordination polymers with sulfonate group: Syntheses, crystal structures and luminescent behaviors

Abstract

In this paper, three Ag-based metal coordination polymers have been synthesized, namely, [Ag(BS)(BPP)2] (1), [Ag(MBS)(BPP)2] (2), and [Ag(ABS)(BPP)2]·H2O (3) (BS = benzenesulfonate, MBS = p-toluenesulfonate, ABS = p-aminophenyl sulfonate, BPP = 1,3-bis(pyridine-4-yl) propane). Metal coordination polymer 1–3 were structurally characterized by X-ray single-crystal diffraction, IR spectra, thermogravimetry analysis (TGA), and X-ray diffraction (PXRD). Through the X-ray single-crystal diffraction analyses, metal coordination polymers 1 and 2 exhibit one-dimensional structural motifs. Interestingly, metal coordination polymer 3 display the mixed one-dimensional and two-dimensional structures. Their thermogravimetric behaviors have been studied. Additionally, the luminescent properties of metal coordination polymers 1–3 were investigated in the solid-state at room temperature in details, which display the maximal emission peaks located at 388, 334 and 450 nm, respectively.
