Abstract
The present invention provides a novel metal complex compound represented by the following general formula (1), and an organic electroluminescence element which has a high efficiency of light emission and a long lifetime, wherein one of organic thin film layers including at least a light emitting layer between an anode and a cathode, at least one of the organic thin film layers contains the metal complex compounds.(L)M(L)  (1)wherein M represents Ir, Pt and Rh; Land Lrepresents mutually different bidentate ligands; (L)M as a partial structure is represented by general formula (2) and M(L)as a partial structure is represented by general formula (3): and m and n are each an integer of 1 or 2, provided that m+n is a integer of 2 or 3. wherein ring A1 represents an aromatic hetrocyclic ring group; and ring B1 represents an aryl group, provided that the ring A1 and the ring B1 are covalently linked to each other via Z which represents a single bond or the like. wherein R, R, R' and Reach independently represent an alkyl group or the like; Rand R, Rand R′, Rand R′, Rand R, and R′ and Rmay combine with each other to form a cyclic structure; and Y represents a group represented by O or S.
