(4′-Ferrocenyl-22′:6′2′′-terpyridine-κ3 NN′N′′)(110-phenanthroline-κ2 NN′)copper(II) bis(perchlorate) acetonitrile solvate

摘要

The title complex, [CuFe(C5H5)(C20H14N3)(C12H8N2)](ClO4)2·C2H3N, consists of a mononuclear [Cu(C12H8N2)(C25H₁₉FeN₃)]²⁺ cation, two ClO₄ ⁻ anions (one of which is disordered over two positions with equal occupancy) and one CH₃CN solvent mol­ecule. The Cu^II center has a distorted square-pyramidal coordination with three N atoms of the 4′-ferrocenyl-2,2′:6′,2′′- terpyridine (fctpy) ligand and one 1,10-phenanthroline (phen) N atom in the basal plane and a second phen N atom in the apical position with an axial distance of 2.254 (4) Å. The disordered ClO₄ ⁻ anion is weakly coordin­ated to the Cu^II ion with a Cu—O distance of 2.766 (11) Å. The two cyclo­penta­dienyl rings of the ferrocenyl group are almost eclipsed with a deviation of 4.7 (1) °, and are involved in inter­molecular π–π inter­actions with the outer pyridyl rings of the fctpy ligands [centroid–centroid distance = 3.759 (2) Å.].
