title: Bis(μ-4,4''-difluoro-1,1':3',1''-terphenyl-2'-carboxylato-κ(2)O:O')bis[aqua(4,4''-di-fluoro-1,1':3',1''-terphenyl-2'-carboxyl-ato-κO)(pyridine-κN)cobalt(II)] diethyl ether disolvate.
abstract: The structure of the title compound, [Co(2)(C(19)H(11)F(2)O(2))(4)(C(5)H(5)N)(2)(H(2)O)(2)]·2C(4)H(10)O, comprises two Co(II) atoms in a distorted square pyramidal coordination environment, straddling a crystallographic inversion center with a Co⋯Co separation of 3.1923 (15) Å. Each Co(2+) cation is coordinated by three O atoms of three 4,4''-difluoro-1,1':3',1''-terphenyl-2'-carboxyl-ate ligands, one water O atom and one pyridine N atom, forming a CoO(4)N polyhedron. Strong intra-molecular O-H⋯O hydrogen bonds are observed between terminal metal-bound carboxyl-ate groups and water O atoms.
