The invention provides a metal complex comprising a ligand and a metal. The ligand is an aminophosphine compound represented by the following formula (1) <CHEM> <??>ÄEach Ar represents an aryl group optionally substituted with a halogen atom, a lower alkyl group having 1 to 4 carbon atom or an alkoxy group, both Ar's being same or different with each other. R<1> and R<2> represent hydrogen atom, a cycloalkyl group having 5 to 7 carbon atoms, or an alkyl group having 1 to 6 carbon atom optionally substituted with a halogen atom, a lower alkoxy group or phenyl group, with R<1> and R<2> being same or different with each other. Alternatively, one of R<1> and R<2> is hydrogen atom and the other is -COR<3> (R<3> represents a cycloalkyl group having 5 to 7 carbon atoms, a lower alkyl group having 1 to 6 carbon atom optionally substituted with a halogen atom, a lower alkoxy group or phenyl group, a substituted or unsubstituted phenyl group, or a lower alkoxy group having 1 to 6 carbon atom optionally substituted with a cycloalkyl group having 5 to 7 carbon atoms, a halogen atom, a lower alkoxy group or phenyl group) or -SO2R<4> (R<4> represents a cycloalkyl group having 5 to 7 carbon atoms, an alkyl group optionally substituted with a halogen atom, a lower alkoxy group or phenyl group, or substituted or unsubstituted phenyl group). n represents 0Ü. The metal is rhodium, ruthenium, iridium or nickel.
