The present invention relates to a method for manufacturing an iridium complex with the high selectivity and the high yield, and to an organic electroluminescent device using an iridium complex manufactured by the method. The iridium complex with a heteroleptic fac-Ir(C^N)_2(C^N)′ structure is manufactured by making an iridium intermediate react with a ligand compound in the presence of a mixed solvent including a halogen-containing solvent and an alcohol-based solvent. 본 발명은 할로겐-함유 용매와 알코올계 용매를 포함하는 혼합 용매의 존재 하에서 이리듐 중간체와 리간드 화합물을 반응시켜 heteroleptic fac-Ir(C^N)(C^N)'구조의 이리듐 착물을 높은 선택성 및 수율로 제조하는 방법, 및 상기 방법에 의해 제조된 이리듐 착물을 이용한 유기 전계 발광 소자에 대한 것이다.
