We report our investigations of the electrical resistivity, Seebeck coefficient, thermal conductivity, and heat capacity on the ternary sulfide NiV2S4 as a function of temperature. All measured physical quantities exhibit pronounced anomalies at around 165K, with a significant hysteresis of about 10K. The results of electrical transport measurements show conventional metallic-like characteristics below and above the transition, indicative of the first-order metal-metal transition in NiV2S 4. The anomalous features of NiV2S4 are compared to those of other thiospinels, and possible origins responsible for the present transition are provided.
