In the title complex, [CuFe(C5H5)(C20H14N3)(C10H8N2)](BF4)2, the Cu II atom is five-coordinated by a tridentate chelating 4′-ferrocenyl-2,2′:6′,2″-terpyridine (fctpy) ligand and a bidentate chelating 2,2′-bipyridine (bpy) ligand. The coordination polyhedron is distorted square-pyramidal with an N atom from the bipyridine ligand in the apical position at a Cu - N distance of 2.195 (3) Å. In the crystal structure, tetra-fluoridoborate counter-ions are involved as acceptors in inter-molecular C - H⋯F hydrogen-bonding inter-actions with both...
