Salts containing cations of the formula: [Figure] (in which M is Co, Fe, Cr or Mn, X, Y, R1, R2 and R4 are hydrogen, alkyl or substituted groups, and the two R3 groups and/or the two R6 groups form an organic bridging group), and derivatives of these compounds having various axial ligands attached t

Salts containing cations of the formula: [Figure] (in which M is Co, Fe, Cr or Mn, X, Y, R1, R2 and R4 are hydrogen, alkyl or substituted groups, and the two R3 groups and/or the two R6 groups form an organic bridging group), and derivatives of these compounds having various axial ligands attached to the metal atom, complex oxygen reversibly and are thus useful for oxygen scavenging and separating oxygen from air. Other types of compounds having similar bridging groups are also useful for the same purpose.

A salt of a cationic metal complex of the formula: [Figure] XVII wherein: M is Co, Fe, Cu, or Mn; n+is a positive oxidation state of M, n being not greater than 3; X and Y are each independently an o-phenylene, ethylene, trimethylene, 2-(2-pyridyl)-trimethylene, 2-methyl substituted trimethylene or

A salt of a cationic metal complex of the formula: [Figure] XVII wherein: M is Co, Fe, Cu, or Mn; n+is a positive oxidation state of M, n being not greater than 3; X and Y are each independently an o-phenylene, ethylene, trimethylene, 2-(2-pyridyl)-trimethylene, 2-methyl substituted trimethylene or 2-(N-methyl-2-pyridino)-trimethylene group; each R1 independently is hydrogen or a methyl group; each R2 independently is hydrogen or a methyl group; each R3 independently is hydrogen, an alkyl group containing not more than about 17 carbon atoms, a benzyl group, a phenyl group, or a phenyl group substituted by a halogen atom or by one or two methoxy groups; or the two R3 groups together form a carbon-carbon bridge, said carbon-carbon bridge comprising a polymethylene bridge containing from 7 to about 12 carbon atoms or an m- or p-xylylene group; each R4 independently is hydrogen, an alkyl group containing not more than about 4 carbon atoms, a cyanoalkyl group containing not more than about four carbon atoms, a phenyl group or a benzyl group; each R6 independently is hydrogen or a methyl group; or the two R6 groups together form a nitrogen-nitrogen bridge, said nitrogen-nitrogen bridge comprising a polymethylene group containing from 4 to about 12 carbon atoms, a polymethylene group containing from 4 to about 12 carbon atoms and substituted by a methoxycarbonyl group, or a grouping of the formula: －(CH2)a－G－(CH2)b－ where a and b are each independently 1, 2 or 3 and G is a 1,3-phenylene group, a 1,4-phenylene group, a methoxy-substituted 1,4-phenylene group, a 9,9-fluorylene group, a 1,3-cyclohexylene group, a 1,4-cyclohexylene group, a sulfur atom, an imino group, or a methylimino group, subject to the proviso that when G is a sulfur atom, a imino group or a methylimino group, the sum of a and b is at least 4; or the two NR4R6 groups together form a bis-piperazino bridge of the formula [Figure] where D is a 1,3-phenylene group, a 1,4-phenylene group, a 1,4-phenylene group substituted by one or more methyl groups, a 9,10-anthracene group or a 2,6-pyridylene group, subject to the proviso that when the two R3 groups do not form a carbon-carbon bridge, either the two R6 groups must form a nitrogen-nitrogen bridge or the two NR4R6 groups must form a bis-piperazino bridge.
