catena-Polytetra­aqua­trans-12-bis­(4-pyrid­yl)ethene-κ2 N:N′nickel(II) dinitrate

摘要

In the title compound, {[Ni(C12H10N2)(H2O)4](NO3)2}n, the Ni^II 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 Ni^II 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.
