Abstract

Two sets of nickel(II) complexes of a series of tetradentate NSNO ligands were synthesized and isolated in their pure form. All these complexes, formulated as $[Ni(L)Cl]_2$ and $[Ni(L)(N_3)]_2$ [HL = pyridylthioazophenols], were characterized using physicochemical and spectroscopic tools. The solid-state structures of two complexes (1a and 2a) were established by X-ray crystallography. The geometry about the nickel ion of the complexes is octahedral and the complexes are dimeric in nature. In 1, two Ni(II) ions are bridged by two $Cl^{-}$ anions while in 2 they are bridged by two azide ions in a \mu -1,1-bridging fashion.
