The present invention relates to a novel organometallic compound, and more particularly, to a luminescent organometallic compound in which intermolecular interaction is inhibited by means of introducing a germanium substituent, thereby improving light-emitting characteristics. The present invention also relates to an organic electronic device, specifically, to an organic light-emitting diode using the compound. According to the present invention, a germanium substituent is introduced to the parent organometallic iridium compound, thus inhibiting an intermolecular interaction in the solid state and enabling the compound of the present invention to be effectively used in solution processing. When the compound of the present invention is used as part of a light-emitting layer of an organic light-emitting diode, the light-emitting efficiency of the light-emitting diode may be significantly improved. Therefore, the compound of the present invention may be effectively used as a material for an organic light-emitting diode.
