title: Mu-1,2-Bis(4-pyridyl)ethene-kappa2N:N'-bis(tetraaqua{4-[2-(4-pyridinio)ethenyl]pyridine-kappaN}cobalt(II)) hexaaquacobalt(II) tetrakis(sulfate) octahydrate.
abstract: The title compound, [Co2(C12H11N2)2(C12H10N2)(H2O)8][Co(H2O)6](SO4)4.8H2O, consists of bis(4-pyridyl)ethenedicobalt(II) cations, hexaaquacobalt cations, sulfate anions and water solvent molecules that are linked by hydrogen bonds into a network structure. In the hexaaquacobalt cation, the six water molecules are coordinated in an octahedral geometry to the Co atom, which lies on an inversion centre. The other cation is a 1,2-bis(4-pyridyl)ethene-bridged centrosymmetric dimer, consisting of protonated 1,2-bis(4-pyridyl)ethene cations, a bridging 1,2-bis(4-pyridyl)ethene ligand and tetraaquacobalt cations. Each Co atom is six-coordinated by four water molecules and two N atoms from a protonated 1,2-bis(4-pyridyl)ethene cation and the bridging 1,2-bis(4-pyridyl)ethene ligand, and the geometry around each Co atom is octahedral.
