Bis(ethylenediamine)nickel(II) dinitrate

J. A. Krause Bauer, S. E. Edison and M. J. Baldwin

Abstract: In the title complex, [Ni(C₂H₈N₂)₂](NO₃)₂, the two ethylenediamine groups, (en), and the nitrate anions are related by an inversion center at the Ni atom. The coordination about the Ni atom can be described as a tetragonally distorted octahedron with four equatorial sites occupied by the N atoms of the (en) groups and the two axial sites by the nitrate anions through a `semi-coordinating' NiO interaction of 2.5539  (15)  Å. The remaining O atoms of the nitrate groups participate in N-HO hydrogen-bonding interactions with the (en) ligand.
