The present invention relates to general formula (I) Wherein structure B is a benzene ring residue having R 1 to R 4, R 1 to R 4 each independently represent H or the like, at least one of R 1 to R 4 is CN group. R 1 and R 2 , R 2 and R 3 , R 3 and R 4 may be bonded to each other to form a ring structure. The structure A represents a ring structure having 3 to 20 carbon atoms including at least one C═N bond, may have a substituent, and may include the R 4 to form a ring structure. M is Ir, Rh, Pt or Pd. And an organic electroluminescent device in which an organic thin film layer comprising at least one light-emitting layer or a plurality of layers is sandwiched between a pair of electrodes. Provided is an organic electroluminescence device having at least one thin film layer containing the metal complex compound, which emits light when a voltage is applied between both electrodes, has high luminous efficiency, and has a long lifetime. |
