Herein, we report the synthesis of new ditopic ligands, which consist of a phenoxy group and N,N,N′-trisubstituted amidines linked by a methylene spacer (L1–L4). Their coordination chemistry has been investigated with Zn(II) and Al(III). Alkane elimination route between the phenol-amidine proligands (L1H–L4H) and Et2Zn led to dinuclear complexes [(L1–L4)ZnEt]2 (1a–4a) in which the Zn centers are chelated

A metal complex is provided which is used for an organic EL device and an organic light-emitting device which outputs light with high luminance and high efficiency. The metal complex has a structure in which a nitrogen atom in a 6- to 8-membered non-aromatic cyclic group is bonded to a metal atom. The organic light-emitting device includes a pair of electrodes which are an anode and a cathode, and an organic compound layer interposed between the electrodes. The organic compound layer contains the metal complex represented by the following structural formula.
