A metal coordination compound suitable as an organic material for a luminescent device is represented by the following formula (1): wherein M denotes Ir, Pt, Rh or Pd; n is 2 or 3; R1 and R2 independently denote a linear or branched alkyl group having 1-20 carbon atoms capable of including one or at least two non-neighboring methylene groups which can be replaced with -O-, -S-, -CO-, -CO-O-, -O-CO-, -CH=CH- or -C=C- and capable of including hydrogen atom which can be replaced with fluorine atom; and CyN denotes a cyclic group containing nitrogen atom connected to M and capable of having a substituent selected from the group consisting of halogen atom; nitro group; phenyl group; trialkylsilyl group having 1-8 carbon atoms; and a linear or branched alkyl group having 1-20 carbon atoms capable of including one or at least two non-neighboring methylene groups which can be replaced with -O-, -S-, -CO-, -CO-O-, -O-CO-, -CH=CH- or -C=C- and capable of including hydrogen atom which can be replaced with fluorine atom.
