摘要：

We describe the synthesis and characterization of a new mononuclear palladium complex (PdL) based on a thiosemicarbazone ligand. X-ray diffraction data collected on single crystals reveal that the complex is a neutral mononuclear entity with symmetric square-planar geometry around the metal center. The complex exhibits an electrocatalytic behavior for proton reduction in DMF solvent using trifluoroacetic acid (TFA) as a proton source. Gas analysis under controlled electrocatalytic conditions during 4 h at a pool mercury working electrode showed a moderate production of dihydrogen. By combining experimental techniques to theoretical calculations, the results are analyzed and compared to those obtained for the previously reported NiL complex in an effort to rationalize the influence of the metal center on the catalytic performance of PdL to mediate hydrogen evolution.
