The first silver–palladium heterometallic complex Pd II[(μ-OOCMe) 2Ag I(HOOCMe) 2] 2 was synthesised from Pd II and Ag I acetates and structurally characterized with single-crystal XRD and quantum-chemical DFT calculations. The complex is thermally transform into Ag х Pd 1− х alloy nanoparticles and can be a useful source for Pd–Ag alloys. [Display omitted] ► First heterometallic Pd–Ag acetate. ► Single-crystal XRD structure. ► Quantum-chemical DFT calculations. ► Thermal transformations produce PdAg alloy nanoparticles. ► XRD and EXAFS characterized the PdAg nanoalloys. The reaction between Pd 3(OOCMe) 6 and Ag 2(OOCMe) 2 afforded the first palladium–silver heterometallic acetate-bridged complex Pd II[(μ-OOCMe) 2Ag I(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 1 in vacuo and under Ar, H 2 produced PdAg alloy nanoparticles characterized with powder XRD and EXAFS.
