X-ray crystal structure, ESR and potentiometric studies of copper(II) complexes with (2-pyridylmethyl, 3-pyridylmethyl) amine ligand
Section snippets
Supplementary material
All chemicals were of reagent grade quality, obtained from commercial suppliers and used without further purification. Elemental analyses for carbon, hydrogen and nitrogen were carried out on a Perkin–Elmer 2400 C, H, N elemental analyser in our University. Chloride analysis was performed potentiometrically using silver nitrate and metal analysis on an ICP AES Liberty Series II Varian apparatus.
Magnetic susceptibilities were determined at room temperature (20 °C) using HgCo(SCN)4 as calibrant;
