Compounds of formula I are useful in the separation of a gas such as oxygen, hydrogen, sulphur dioxide, alkenes and carbon monoxide from a fluid comprising the gas. MnIILX2I In formula I:L represents a monodentate ligand of formula IA and X is a species capable of existing as an anion PR1R2R3Ia wherein R1, R2 and R3 which may be identical or different represent substituted or unsubstituted alkyl, cycloalkyl or aryl groups or hydrogen and X represents －Cl, －Br, －I, －CN, －NO2, －NO3, －OH, －NCS or －NCO provided that no more than two of the groups R1, R2 and R3 are substituted or unsubstituted aryl groups and that at least one of the groups R1, R2 and R3 is a substituted or unsubstituted alkyl, cycloalkyl or aryl group.
