Novel heterometallic palladium–silver complex

The reaction between Pd3(OOCMe)6 and Ag2(OOCMe)2 afforded the first palladium–silver heterometallic acetate-bridged complex PdII[(μ-OOCMe)2AgI(HOOCMe)2]2 (1). The molecular geometry and electronic structure of 1 were studied by single-crystal XRD and quantum-chemical DFT calculations. Thermal transformations of 1in vacuo and under Ar, H2 produced PdAg alloy nanoparticles characterized with powder XRD and EXAFS.

The first silver–palladium heterometallic complex PdII[(μ-OOCMe)2AgI(HOOCMe)2]2 was synthesised from PdII and AgI acetates and structurally characterized with single-crystal XRD and quantum-chemical DFT calculations. The complex is thermally transform into AgхPd1−х alloy nanoparticles and can be a useful source for Pd–Ag alloys.Figure optionsDownload as PowerPoint slideResearch highlights
