The title compound, [Ni(NCS)2(C9H8N2)4], crystallizes with two independent half-mol­ecules in the asymmetric unit and the NiII ions situated on centres of symmetry. In both independent mol­ecules, the NiII ion displays a compressed octa­hedral environment formed by four N atoms from the 1-phenyl-1H-imidazole ligands, which define the equatorial plane, with a mean Ni—N distance of 2.119 (11) Å, and two axial N atoms from two NCS− anions, with a mean Ni—N distance of 2.079 (7) Å. The crystal packing exhibits weak inter­molecular S⋯S contacts of 3.411 (2) Å.
