Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
New iron(III) and manganese(III) complexes were synthesized by the condensation of 1-phenyl-1,3-butanedione-S-propyl-thiosemicarbazone ( 1 ) with salicylaldehyde in the presence of iron(III) or manganese(II) ions. The complexes were characterised by analytical and spectroscopic methods. X-ray analysis displayed the square pyramidal environments of the iron and manganese ions. The electrochemical behaviors of the iron(III) ( 1a ) and manganese(III) ( 1b ) complexes were studied by cyclic voltammetry and square wave voltammetry in different solvents. Both complexes displayed metal-based electron transfer reactions in addition to ligand based irreversible reduction and oxidation processes, which were affected by the type of metal. Spectroelectrochemical methods were used to examine the electrogenerated species of the complexes and to define the redox processes. The total antioxidant capacity (as the TEAC value) and free radical scavenging activities (FRS%) of the compounds were determined. The TEAC values of 1 (2.78), 1a (1.63) and 1b (1.28) are higher than those of vitamin C (0.96).
