A new silver(I) coordination polymer containing 3-methylthio-(1H)-1,2,4-triazole as precursor for preparation of silver nanorods

•Synthesis and characterization of a novel silver(I) coordination polymer containing 3-methylthio-(1H)-1,2,4-triazole (MTTz).•MTTz ligands show two different tautomeric forms in complex 1.•Application of silver(I) coordination polymer as precursor for preparation of silver nanorods.

The reaction of 3-methylthio-(1H)-1,2,4-triazole (MTTz) with silver(I) nitrate in a molar ratio 2:1 in MeOH/CH3CN led to the coordination polymer {[Ag2(MTTz)4](NO3)2}n (1). The coordination polymer 1 has been characterized by FTIR- and 1H NMR-spectroscopy, ESI-MS spectrometry and elemental analysis as well as single crystal X-ray diffraction. The luminescence measurements have also been carried out. Furthermore, the thermal stability of complex 1 was studied by thermal gravimetric (TG) and differential thermal analyses (DTA). Solventless thermolysis of complex 1 at 600 °C under air atmosphere led to the formation of silver nanorods. The silver nanostructures were characterized by a series of techniques including X-ray powder diffraction (XRD), energy-dispersive X-ray (EDX) and scanning electron microscopy (SEM).
