Abstract

Graphical abstract: Cs-K-Pd3 (PW9 )2 was synthesized from individual salts, determined by single crystal XRD and used as catalyst for hydrogenation of nitrobenzene . Highlights: Tri-palladium substituted sandwich type phosphotungstate synthesized as a single isomer. Detail structural elucidation for the first time by single crystal XRD and spectral analyses. Scope of the material as catalyst for selective hydrogenation of alkenes and nitro group. Abstract: The present work showcases, first time, the synthesis of tri-palladium substituted sandwich type phosphotungstate, [Pd3 (PW9 O34 )2 ] 11−, from its individual salts in super acidic medium as well as the single crystal structure of the same. Further, various spectral analysis carried out to support the crystal data. A preliminary study for the hydrogenation of nitrobenzene has been carried out to evaluate the catalytic activity of the complex.
