Bis[bis(ethylenediamine-N,N')(μ_N,S-thiocyanato)nickel(II)] Bis(hexafluorophosphate)

The title compound, [Ni₂(NCS)₂(C₂H₈N₂)₄](PF₆)₂ or [Ni(en)₂(μ_N,S-NCS)]₂[PF₆]₂ (en = ethylenediamine), has been synthesized via a molecular rearrangement reaction of trans-Ni(en)₂(NCS)₂. It consists of dibridged [Ni(en)₂(μ_N,S-NCS)]₂ cations with the NCS ligands forming a cis arrangement at the nickel centres. A three-dimensional intermolecular hydrogen-bonding network is observed between the amine protons of the en ligands and the F atoms of the PF₆⁻ anions.
