Abstract: An organometallic compound represented by Chemical Formula I, wherein in the Chemical Formula I, M represents a central coordination metal, and includes one selected from the group consisting of molybdenum (Mo), tungsten (W), rhenium (Re), ruthenium (Ru), osmium (Os), rhodium (Rh), iridium (Ir), palladium (Pd), platinum (Pt), and gold (Au), A represents one ring structure selected from pyridine and pyrimidine, where the ring structure is optionally substituted with deuterium, and each of R1 to R8 independently represents one selected from the group consisting of hydrogen, deuterium, a substituted or unsubstituted C1 to C20 linear alkyl group, a substituted or unsubstituted C3 to C20 branched alkyl group, and a substituted or unsubstituted C4 to C20 bicycloalkyl group.

Abstract: An organometallic compound represented by Chemical Formula I, and an organic light-emitting diode containing the same. In the Chemical Formula I, M may represent a central coordination metal, and includes one selected from a the group consisting of molybdenum (Mo), tungsten (W), rhenium (Re), ruthenium (Ru), osmium (Os), rhodium (Rh), iridium (Ir), palladium (Pd), platinum (Pt), and gold (Au). Each of R1 to R8 may independently represent one selected from the group consisting of hydrogen, deuterium, a substituted or unsubstituted C1 to C20 alkyl group, and a substituted or unsubstituted C3 to C20 bicycloalkyl group. A may represent a ring structure of isoquinoline. Each of X1 to X4 may independently represent one selected from CR11 and nitrogen (N).
