Divalent cobalt complexes of tetradentate N2Py2 incorporating a pendant base moiety in the second coordination sphere have been synthesized and studied electrochemically for catalytic activity towards H+ and O2 reduction. Progress toward proton reduction has been studied using H2O, [PhNH3][BF4], and [HDMF][OTf] in organic solvents. A divalent nickel complex of DHMPB (1,2-Bis(dihydroxy dimethylphosphino)benzene) has been synthesized and tested as an electrocatalyst for proton reduction using [HTMG][BF4] and [PhNH3][BF4] in organic solvents.
