Recently layered compound TaNiTe5 was proposed to be two-dimensional (2D) topological semimetals. Here we report the detailed investigation on TaNiTe5 single crystals through magnetotransport and de Hass−van Alphen (dHvA) effect studies. Strong quantum oscillations with multiple periodicities have been observed. By analyzing the quantum oscillations, we provide evidence of nontrivial Berry phase with a 3D Fermi surface character in layered TaNiTe5. Our work suggested that layered TaNiTe5 should be 3D topological semimetal which offers a platform to explore exotic properties in low-dimensional topological semimetals.
