Abstract

A composition of matter suitable for the generation of hydrogen from water is described, the positively charged cation of the composition including the moiety of the general formula. [(PY5Me 2 )CoL] 2+ , where L can be H 2 O, OH − , a halide, alcohol, ether, amine, and the like. In embodiments of the invention, water, such as tap water or sea water can be subject to low electric potentials, with the result being, among other things, the generation of hydrogen.

Claims (6)

1. An organo metal complex of the following formula:

M=Co

U, V, W, X, Y, and Z are H, R, a halide, CF 3 , SiR 3 , where R can be an alkyl or aryl group

L can be H 2 O, OH − , halide, alcohol, ether, thioether, amine, phosphine, nitrile, thiol, alkoxide, cyanide, isocyanide, azide, thiocyanate, aryl or alkyl sulfonate, phosphate, nitrate, sulfate
