Abstract

A pyrazine bridged ruthenium/palladium bimetallic photocatalyst with peripheral 4,4′-dicarboxyethyl-2,2′-bipyridine ligands, EtOOC-RuPd, is reported, together with its 2,2′-bipyridine analogue. Upon irradiation with visible light, EtOOC-RuPd catalyses the production of hydrogen gas whereas the complex RuPd does not.
