Igand[4-(8-hydroxyquinolin-5-yl),diazenyl)benzoic acid] (HQDbA) is a novel heterocyclic azo dye that was created by reacting 4-amino benzoic acid with an ethanolic mixture of 8-hydroxy quinolines. We used spectroscopy to study its metal complexes with Cu(II), Cd(II), Hg(II), and Pd(II) ions. Azo ligands and their related metal complexes have been characterized using a range of spectral techniques, such as mass spectrometry, FT-IR, UV-vis, atomic absorption, molar conductance measurements, and C.H.N. elemental analysis. The Pd(II) ion in these complexes has a square planar shape, and the chelate type is 1:1 [M:L] chelates. Cu(II), Hg(II), and Cd(II) ions were proposed to have an octahedral geometry as 1:2 [M:L] chelates.. The di-ions of Pb, Pd, Hg, Cd, and Cu that form metal complexes are compared to the IV effects of the Pt(II) complex in biological screening. Based on the data, the chelate composition of "1:2" [M:L] for each of the Cd(II), Cu(II), and Hg(II) ions was established. The complexes have an octahedral shape. Additionally, these complexes have a chelates composition of (1:1)[M:L] and exhibit a square planar geometry for the Pd(II) ion. Considering that the Pt(II) complex's biological screening effect is assessed in connection with.
