High capacity solid state compositions comprising cyanocobaltate complexes have been developed which are capable of reversibly chemically binding oxygen to selectively remove oxygen from an oxygen-containing fluid stream. The cyanocobaltate complexes which make up the compositions comprise a cobalt (II)-containing anion having from 3 to 5 cyanide ligands wherein at least one cyanide stretching mode, as measured by infrared spectroscopy, is between 2074 cm⁻¹ and 2140 cm⁻¹. Additionally, these complexes have a charge-balancing cation having a molecular volume in excess of 40ų.
