Homogeneous light-driven systems
employing molecular molybdenum
catalysts for hydrogen production are described. The specific Mo complexes
studied are six-coordinate bis(benzenedithiolate) derivatives having
two additional isocyanide or phosphine ligands to complete the coordination
sphere. Each of the complexes possesses a trigonal prismatic coordination
geometry. The complexes were investigated as proton reduction catalysts
in the presence of [Ru(bpy)3]2+, ascorbic acid,
and visible light. Over 500 TON are obtained over 24 h. Electrocatalysis
occurs between the MoIV/MoIII and MoIII/MoII redox couples, around 1.0 V vs SCE. Mechanistic
studies by 1H NMR spectroscopy show that upon two-electron
reduction the Mo(CNR)2(bdt)2 complex dissociates
the isocyanide ligands, followed by addition of acid to result in
the formation of molecular hydrogen and the Mo(bdt)2 complex.
