Copper (II) chloride (CuCl 2 )(0.134 g, 1 mmol) was dissolved in 2 ml concentrated hydrochloric (HCl) acid (37 %) and similarly 1H-1,2,4-triazole (0.069 g, 1 mmol) was dissolved in 2 ml concentrated HCl (37 %). The two solutions were mixed and maintained at room temperature in a 20 ml glass vial. After 10-12 hours, single crystals, like in Figure , were obtained at the bottom of the vial. Figure shows the Raman spectra of the synthesized coordination polymer and 1H-1,2,4triazole measured using a green laser with a wavelentth of λ = 514.5 nm focused on a single crystal. The Raman spectrum of 1H-1,2,4-triazole is consistent with the literature reports . In the spectrum of the coordination polymer (plotted in green) the peaks located at 1075, 1141 and 1315 cm -1 indicated by the vertical dashed lines are attributed to the C-H bending, ring breathing, and ring stretching modes, respectively. To the best of our knowledge, there was no report of Raman spectroscopy on this coordination polymer.
