Preparation, Electronic Properties, and Powder-XRD Structure Analysis of 3,5-Bis(pyridin-2-yl)-H-1,2,4-triazoledichloridocopper(II)

Salt of [Cu(bptrzH)Cl2], (bptrzH = 3,5-bis(pyridin-2-yl)-H-1,2,4-triazole) has been prepared and characterized its electronic spectral and magnetic properties. This salt is paramagnetic with magnetic moment, μs, being 1.77–1.78 BM at 293 K, but decreased significantly with decreasing temperature to...
