Abstract
In the title compound, {[Ni(C12H10N2)(H2O)4](NO3)2}n, the NiII ion, lying on a crystallographic inversion center, has a distorted octahedral coordination sphere comprising four water ligands and two N-atom donors from the trans-related 1,2-bis(4-pyridyl)ethene ligands, which also have crystallographic inversion symmetry. These ligands bridge the NiII complex units, forming chains extending along the [110] and [10] directions. The nitrate counter-anions stabilize the crystal structure through water–nitrate O—H⋯O hydrogen bonds.
