A novel cyclam–nickel(II) complex appended with a tris-(2,2′-bipyridine) ruthenium(II) complex (cyclam = 1,4,8,11-tetra-azacyclotetradecane)

Abstract
A new class of heterometallo-binuclear complex [RuII(bpy)2(bpy–cyclam)NiII]4+(3)(bpy = 2,2′-bipyridine) has been synthesized as a new complex for use in photocatalysts; NMR and X-ray structural studies show a close contact between a hydrogen atom of the pendant bpy and NiII in the cyclam.
