Claimed is a cyclometallated organometallic light emitting complex having two tridentate ligand portions sharing a central heterocycle “A” providing a binding-site for each of the two metals (formula I): Formula (I): A more illustrative embodiment is formula (XII): Characterizing for the invention is that either one of XI and X2 and either one of Y1 and Y2 is carbon. The dinuclear complexes are for use in OLEDs.
