(4′-Ferrocenyl-2,2′:6′,2′′-terpyridine-κ(3) N (1),N (1′),N (1′′))(1,10-phenanthroline-κ(2) N,N′)zinc(II) bis­(perchlorate) acetonitrile monosolvate

In the title complex, [FeZn(C(5)H(5))(C(20)H(14)N(3))(C(12)H(8)N(2))](ClO(4))(2)·CH(3)CN, the Zn(II) atom is five-coordinated by a tridentate chelating 4′-ferrocenyl-2,2′:6′,2′′-terpyridine (fctpy) ligand and a bidentate chelating 1,10-phenanthroline (phen) ligand in a distorted square-pyramidal environment with a phen N atom located at the apical position [Zn—N = 2.259 (4) Å]. The terpyridyl motif in each fctpy ligand is coplanar, but the cyclo­penta­dienyl ring is twisted by 9.5 (2)° out of coplanarity with each central pyridine. The two cyclo­penta­dienyl rings of the ferrocenyl group are almost eclipsed with a deviation of 4.5 (1)°. In addition, inter­molecular π–π inter­actions [centroid–centroid distance 3.753 (2) Å] are present between the cyclo­penta­dienyl and outer pyridyl rings of the fctpy ligands. One of the perchlorate anions is equally disordered over two positions.
