Metals with kagome lattice provide bulk materials to host both the flat-band and Dirac electronic dispersions. A new family of metals is recently discovered in AV6Sn6. The structures this material need more experimental evidence confirm. In manuscript, we investigate problem by resolving quantum oscillations electrical transport magnetization ScV6Sn6. revealed orbits are consistent band structure models. Furthermore, Berry phase a dominating orbit be around $\pi$, providing direct for topological structure, which calculations. Our results demonstrate rich physics shed light on correlated ground state metal.
