chemical properties of these complexes were investigated using X-ray crystallography, UV–vis and NMR spectroscopy, and cyclic voltammetry. In the solid-state, the Ni(II) complexes adopt a unique bimetallic and cis-octahedral (μ-Cl)2 coordination sphere, and the electronic studies provide further evidence for the existence of a six-coordinate Ni(II) species in solution. The pyridol-based Cu(II) and Zn(II)
