1. A method for producing a redox-active coordination compound of a transition metal selected from the group consisting essentially of titanium, aluminum, chromium, iron, vanadium, manganese, cerium, and uranium which comprises:

  • (a) precipitating a soluble salt of the transition metal with a base in an aqueous reaction medium to form freshly precipitated hydrous transition metal oxide;

    (b) separating the freshly precipitated hydrous transition metal oxide from the aqueous reaction medium; and

    (c) reacting the freshly precipitated hydrous transition metal oxide with a chelating agent and a base in a second aqueous reaction medium to produce a solution of the corresponding redox-active transition metal coordination compound.
