The reactions of the organodichalcogenone ligands Bbit[1,1′‐(butane‐1,4‐diyl)bis(3‐methylimidazoline‐2‐thione)],Mbis [1,1′‐methylenebis(3‐methylimidazoline‐2‐selone)], Ebis [1,1′‐(ethane‐1,2‐diyl)bis(3‐methylimidazoline‐2‐selone)] and Pbis [1,1′‐(pentane1,5‐diyl)bis(3‐methylimidazoline‐2‐selone)] with gold(I/III), silver(I) and copper(I) have been studied by elemental analysis, multinuclear (1H, 13C, 19F, 31P and 77Se) NMR spectroscopy and for several products obtained the molecular structures were also established by single‐crystal X‐ray diffraction analysis. In most cases the organodichalcogenone coordinates to two metallic fragments as a bidentate bridging ligand but the ligand Mbis coordinates to silver(I) in an unprecedented tetradentate bridging‐chelate mode.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
