Construction of triangular metallomacrocycles: [M3(1,2-bis(2,2′∶6′,2″-terpyridin-4-yl-ethynyl)benzene)3] [M = Ru(ii), Fe(ii), 2Ru(ii)Fe(ii)]

Complexation of a predesigned (1,2-bis(2,2':6',2''-terpyridin-4-yl-ethynyl)benzene) ligand possessing a 60 degrees angle between two terpyridines with transition metals [Fe(II) and Ru(II)] afforded the self-assembled, triangular metallomacrocycles.
