A few specially constructed Ru α-diimine complexes have also shown enormous potential in the biomedical field. Several Ru-diimine complexes are well known for their catalytic activity. In this context, the simplest α-diimine system is 1,4-diaza-1,3-butadiene, abbreviated as (DAB/DAD), which received the greatest attention from the research communities. DAB ligands are redox-active. DAB ligands typically function as effective electron donors by employing lone pairs of nitrogen atoms and the π-electrons of the C=N bonds while coordinating the metal ion. The structural, electronic, and photophysical properties of the metal-mediated (DAB) complexes largely depend on the substitution of the ligand backbone as well as metal precursors. A versatile ‘redox noninnocent’ 1,4-diaza-1,3-butadiene motif can stabilise different oxidation states of ruthenium metal depending on the reaction conditions and the presence of co-ligands. The comparative studies of the structural and electrical characteristics of diverse ruthenium-DAB compounds are intriguing, which opens up a new route for researchers to utilise them in a variety of application domains. It is challenging and fascinating to determine the precise electronic structure of redox noninnocent diimine complexes in the presence of a ‘redox active’ metal like ruthenium. In this concise review, we provided a brief overview of the structural and electrical features of various Ru DAB complexes that solely comprise (–N=CH–CH=N–) fragments in the skeleton.</p>","PeriodicalId":759,"journal":{"name":"Russian Journal of Coordination Chemistry","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2024-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142182845","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
