Synthesis, Characterization and Crystal Structure of Cobalt(III) Complex with 2-(2-Thienylidene)-2-Hydroxybenzoylhydrazide

In ethanol, a mononuclear cobalt(II) complex incorporating 2'-(2-,Thienylidene)-2-Hydroxybenzoylhydrazide has been synthesized and characterized by IR, UV-Vis, elemental analysis and X-ray crystal structure analysis. The crystal belongs to triclinic system, space group P (1) over bar with cell constant, a = 1.230 69(10) nm, b=1.329 18(11) nm, c=1.33056(l. 1) nm, alpha=113.702(2)degrees, beta=91.590(2)degrees, gamma=100.846(2)degrees, V=1.9444(3) nm(3), Z=2, mu=0.662 nm(-1), D-c = 1.482 g center dot cm(-3), F(000) = 896, R-int = 0.048 7. The crystal structure shows an anionic didentate ligand 0 and N donors in this work. The cobalt(III) atom is hexacoordinated with oxygen atom from keto group and nitrogen atom from amide to form a cobalt atom for the core octahedral structure. CCDC: 748882.
