SYNTHESIS AND STRUCTURE OF A Cr(III) COMPLEX WITH 2,6-DIACETYLPYRIDINE-BIS(PHENYLHYDRAZONE)

<p>Knowledge of the coordination chemistry of 2,6-diacetylpyridine-bis(phenylhydrazone) (L) is limited, and this compound seems promising in many fields. We explored the reaction of methanolic solutions of chromium(III) nitrate and L in a 1:1 molar ratio and obtained the thin red crystals of the complex. It was characterized by FTIR, elemental analysis, and molar conductivity. Comparing the ligand and the complex spectra confirmed that coordination has occurred through azomethine and pyridine nitrogen atoms. Molar conductivity of DMF solution indicates that the complex is an electrolyte of the type 1:1. The chromium(III) is most likely situated in an octahedral environment of six nitrogen atoms of the two ligand anions, viz. [Cr(L–H)<sub>2</sub>]NO<sub>3</sub>. These findings enable the further investigation of the complex properties. Besides, future research will explore the impact of changing synthetic conditions on the reaction product and their characterization. </p>
