Synthesis and characterization of nickel-, palladium- and platinum(II) complexes of three o,o '-dihydroxydiarylazo dyes: Determination of the coordination geometry of this comprehensive series of tridentate diaryl dye complexes by combining results f

摘要

The syntheses of the square-planar platinum(II) complexes [Pt(L)(tba)] (L = 5,5'-dichloro-2,2'-dihydroxyazobenzenate (dhab), (5-chloro-2-hydroxyphenylazo)-3-oxo-N-phenylbutanamidate (hpab) or (5-chloro-2-hydroxyphenylazo)-2-naphtholate (hpan) and (tba) = tributylamine) is reported, together with those of the complete set of analogous complexes [M(L)(py)] (M = nickel(II), palladium(II), platinum(II) and (py) = pyridine).
