(2,2′-bipyridine-κ2N,N′)(4′-ferrocenyl-2,2′:6′,2"-terpyridine-κ3N,N′,N")copper(II) bis(tetrafluoridoborate)

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) angstrom. In the crystal structure, tetrafluoridoborate counter-ions are involved as acceptors in intermolecular C-H center dot center dot center dot F hydrogen-bonding interactions with both the bipyridyl and terpyridyl ligands, resulting in a three-dimensional supramolecular structure.
