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

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 ]·H 2 O ( 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.
