the Co(II) ion centers of complexes

exhibit similar tetrahedral coordination configurations

through solid UV-Vis and Mott-Schottky tests
it was found that complexes

belong to semi-conductive materials
which have a strong absorption effect on ultraviolet-visible light and can accelerate the degradation rate of acid yellow dyes.
