cis-Aquabis(2,2′-bipyridine-κ2N,N′)fluoridochromium(III) bis(perchlorate) dihydrate

Abstract

The title mixed aqua–fluoride complex, [CrF(C10H8N2)2(H2O)](ClO4)2·2H2O, has been synthesized by aquation of the corresponding difluoride complex using lanthanide(III) ions as F− acceptors. The complex crystallizes with a CrIII ion at the center of a distorted octahedral coordination polyhedron with a cis arrangement of ligands. The crystal packing shows a hydrogen-bonding pattern involving water molecules, the coordinated F atom and the perchlorate anions
