摘要：

Reconstitution of native and ruthenium-modified sperm whale myoglobins (Mb and Ru(3)Mb) with [Os-II(MIX)(CO)(EtOH)] (MIX = mesoporphyrin IX - dicarboxylic acid) and [Os-II(MIX)(DMF)(2)] yields carbonyl osmoglobin ([Os-II(CO)][Mb]) and oxidized osmoglobins ([Os-III][Mb], [Os-III][Ru(3)Mb]). The visible spectrum of [Os-II(CO)][Mb] exhibits alpha and beta bands at 538 and 510 nm, respectively. The ascorbate reduction of dioxygen to water is catalyzed by [Os-III][Ru(3)Mb].
