PURPOSE: A process for preparing a novel complex compound having a band gap corresponding to a blue colour and a high melting point and an organic electroluminescent device are provided which improve thermal stability when applied to electroluminescent devices. CONSTITUTION: An organic metal complex represented by the general formula 1, an organic electric field electroluminescent device comprising a layer containing the complex between the positive and negative poles and processes for preparing thereof are described. In formula, R1,R2,R3 are each independently or simultaneously substituents selected from the group consisting of H, lower hydrocarbon, halogen, alkoxy, arylamine, nitro, nitryl, aldehyde, ester, sulfurous hydrocarbon(-SR), aromatic hydrocarbon, and C1-12 hetero ring compounds; ring A is a ring compound selected from the group consisting of an aromatic comprising a nitrogen atom of an imidazole group and an adjacent carbon atom, an aromatic containing C5-12 hetero ring and C4-11 hetero ring containing N-R4 (R4 is a substituent selected from the group consisting of H, lower hydrocarbon, saturated aliphatic hydrocarbon, and aromatic ring compound; the ring B is a ring compound selected from an aromatic which combines with a carbon atom of an imidazole group or a C5-12 hetero ring; M is a metal selected from the group consisting of beryllium, zinc, magnesium, aluminium, gallium, and indium; n is an integer from 2 to 3.
