| Abstract: | Summary Synthesis, characterization and oxygen affinity studies for Mn(depe)2X2] X=Br or NCS; depe=1,2-bis(diethylphosphino)ethane] complexes are reported. Mn(depe)2Br2] crystals were obtained and characterized by single crystal x-ray and elemental analysis. Gravimetric and volumetric dioxygen uptake studies were performed at atmospheric pressure at various temperatures. These transition metal compounds show considerable dioxygen uptake at various partial pressures of dioxygen. Some isotherm and kinetic data for dioxygen coordination by these complexes at ambient pressures are presented. |
