The structure of the title compound, [Ni(NCS)2(C6H8N2)4], consists of isolated molecules of [Ni(NCS)2(Aim)4] (Aim = 1-allylimidazole), which contain a distorted octahedral NiN6 chromophore. The NCS− anions are trans and four N atoms from the 1-allylimidazole ligands define the equatorial plane. The mean Mn—N(Aim) and Mn—N(NCS) distances are 2.105 (2) and 2.098 (2) Å, respectively. Weak C—H⋯N interactions contribute to the crystal packing stability.
In the corresponding nickel compound [Ni(NCS)2(1-methylimidazole)4] (Liu et al., 2005 ▶), the NiII ions have a distorted octahedral environment.
