fac-Triaqua(2,2′-bipyridine-κ2 N,N′)(nitrato-κO)cobalt(II) chloride

Abstract

The asymmetric unit of the title complex, [Co(NO3)(C10H8N2)(H2O)3]Cl, consists of a chloride anion and a complex cation, which is built on a monodentate nitrate anion, three water molecules and one bidentate 2,2′-bipyridine molecule, coordinated to a CoII cation, in a distorted octahedral geometry. The water molecules are arranged in a facial geometry, and serve as donors for hydrogen bonding. Acceptor sites in the crystal are chloride ions and one O atom of the coordinating nitrate ion. A three-dimensional framework is formed, based on O—H...O and O—H...Cl contacts.
