(4'-Ferrocenyl-2,2':6',2''-terpyridine-?N,N,N)(1,10-phenanthroline-?N,N')zinc(II) bis-(perchlorate) acetonitrile monosolvate.


ABSTRACT: 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 cyclo-penta-dienyl ring is twisted by 9.5?(2)° out of coplanarity with each central pyridine. The two cyclo-penta-dienyl rings of the ferrocenyl group are almost eclipsed with a deviation of 4.5?(1)°. In addition, inter-molecular ?-? inter-actions [centroid-centroid distance 3.753?(2)?Å] are present between the cyclo-penta-dienyl and outer pyridyl rings of the fctpy ligands. One of the perchlorate anions is equally disordered over two positions.
