Data confidence 70 medium

How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Four metal complexes, IL‐OPPh2‐Ru‐p‐cymene (3), IL‐OPPh2‐Ru‐benzene (4), IL‐OPPh2‐Ir‐Cp* (5), IL‐OPPh2‐Rh‐COD (6), have been evaluated for in vitro antioxidant activity such as 2,2‐diphenyl‐1‐picrylhydrazyl (DPPH) radical scavenging and reducing power activity. Maximum scavenging activity (71.43%) was obtained with IL‐OPPh2‐Ru‐p‐cymene, whereas IL‐OPPh2‐Rh‐COD showed the highest reducing power ability. The complexes were also studied for their antimicrobial activity against three Gram‐positive and three Gram‐negative bacteria. In addition, DNA binding of the complexes was evaluated using calf thymus DNA. Both Ru(II) complexes exhibited good DNA‐binding activity while the other complexes did not have any activity. Furthermore, ab initio quantum calculations of four complexes were also carried out using density functional theory to better understand their chemical behaviors.
