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.
