In the centrosymmetric mononuclear title complex, [Ni(NCS)(2)(C(11)H(11)N(3)O)(4)], the Ni(II) atom, located on an inversion centre, is hexa-coordinated in a distorted octa-hedral geometry comprising four N atoms of four monodentate 1-phenyl-3-(1H-1,2,4-triazol-1-yl)propan-1-one ligands and two N atoms from thio-cyanate anions.
