Abstract: 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, tetrafluoridoborate counter-ions are involved as acceptors in intermolecular C-HF hydrogen-bonding interactions with both the bipyridyl and terpyridyl ligands, resulting in a three-dimensional supramolecular structure.
