Overview

Synthesis of metal complexes examined antioxidant activities against DPPH free radicals, indicating variable efficacy.

Key Points

  • All synthesized metal complexes exhibited notable antioxidant activity against DPPH.
  • At varying concentrations, cobalt, nickel, and copper showed less scavenging activity compared to vitamin C.
  • Analysis using UV spectrometry revealed the synthesized complexes had good yield and distinct colors.
  • Proposed octahedral geometry reflects the structural characteristics of these metal complexes.
