An organometallic complex emitting blue phosphorescence which can be manufactured inexpensively is provided. An organometallic complex in which nitrogen at the 1-position of a 5-aryl-4H-1,2,4-triazole derivative is coordinated to a Group 9 metal or a Group 10 metal, the aryl group is bonded to the Group 9 metal or the Group 10 metal, and the 5-aryl-4H-1,2,4-triazole derivative is a 3-aryl-5,6,7,8-tetrahydro-4H-[1,2,4]triazolo[4,3-a]pyridine derivative is provided. The organometallic complex emits green to blue phosphorescence and has a cost advantage.

It is already known that ethyl ω-chloroalkylimidate hydrochlorides and aroyl hydrazides gave, when reacted together in boiling ethanol, 2-aryl-5-ω-haloalkyl-1,3,4-oxadiazoles.It has now been found that the reaction follows a different course in the presence of triethylamine.In particular, 2-aryl-5,6,7,8-tetrahydro-1,2,4-triazolopyridines were obtained from ethyl δ-chlorovalerimidate, whereas N-aroylaminoiminopyrrolidines are the products obtained from ethyl γ-chlorobutyrimidate.A similar case, in which the closure of the triazole ring to obtain a dihydropyrrolotriazole was found to be more difficult than the corresponding closure to a tetrahydrotriazolopyridine, is described.Also the reaction between the imidates and carbethoxyhydrazine, which gives piperidine and pyrrolidine derivatives, is reported.
