New organocobaloximes with biphenylglyoxime ligands: Synthesis,spectroscopic and structural characterization

Abstract

New organocobaloximes of the types, [RCo(HL)₂H₂O] and [RCo(HL)₂APy] (R=izopropyl and benzyl, H₂L¹=4-(4-chlorophenylamino)biphenylglyoxime, H₂L²=4-(naphtyl-1-amino)biphenylglyoxime, APy=2-acetyl pyridine) have been synthesized and characterized by elemental analysis, magnetic susceptibility, molar conductivity, ¹H-NMR, FT-IR, ICP-OES data. In addition, the thermal decomposition of complexes with H₂L² was studied in nitrogen atmosphere. The magnetic susceptibilities of the complexes indicated that they are diamagnetic (low-spin d⁶ octahedral).
