Synthesis, Spectral Characterization, Crystal Structure, and Antioxidant Properties of novel Palladium(II) Complex from ONS Donor 1,5-bis(2-hydroxybenzylidene)thiocarbohydrazone

A new Pd(II) complex, [Pd(PPh3)(L)] (L = 1,5-bis(2-hydroxybenzylidene)thiocarbohydrazone, PPh3 triphenylphosphine), was synthesized and characterized by FTIR, 1H NMR UV-Vis spectroscopies elemental analysis. The molecular structure of confirmed the single-crystal X-ray diffraction technique. Palladium ion has distorted square planar geometry according to studies. free thiocarbohydrazone (L), potentially a pentadentate ONSNO donor, acted as tridentate ONS donor. antioxidant capacity complex determined using CUPRAC (cupric reducing capacity) method. Also, DPPH method used test radical scavenging activity complex. Antioxidant studies showed that exhibited better than
