Topological semimetals have attracted broad interest in recent years. These exotic phases of matter include type-I/II Dirac/Weyl semimetals as well as topological nodal-line semimetals. However, it is relatively rare for a single condensed matter system to possess two or more topological semimetallic states. Here, using angle-resolved photoemission spectroscopy and density functional theory calculations, we show that the nonmagnetic phase of monoclinic V 3 S 4 hosts both type-II Dirac…
