J Vet Res., 23 (2):143-160, 2019. Gold (III) compounds have been
synthesized In vitro to not affect normal physiological functions but to
be highly cytotoxic to human tumor cell lines. Gold (III)
(Au) complexes
were synthesized from 2-(4-antipyrine azo)-4-nitroaniline (C17H15O3N6)
as primary ligand, and oxalic acid, malonic
acid and sodium pyrophosphate
as secondary ligands with (1:1) mole ratio [Au(C17H15O3N6)Cl2],
[Au(C17H15O3N6)(ox)], [Au (C17H15O3N6)(ma)]
and [Au(C17H15O3N6)(pyph]. The complexes were identified by elemental
microanalysis, magnetic moment, mass spectroscopy, molar conductivity and
melting point. The complex products had square plane geometry quantitatively
measured at 610 nm at optimal reaction. Results suggested that
2-(4-antipyrineazo)-4-nitroaniline, oxalic and malonic acids and sodium
pyrophosphate behave as bidentate ligands with Au (III) ion. Geometrical
structure was based on data from previous techniques. We find that
2-(4-antipyrineazo)-4-nitroaniline detector can be used in spectral analysis to
estimate micrograms of Gold ions as it complexes with colored solutions or
sediments resulting in super absorbent peaks within calibration curves for each
ion.
