Parallelly aligned spins in Co‐Kagome nets have provided several reasons for researchers to celebrate: Liu et al. and Wang et al. have reported discoveries of unique combinations of properties: Sn 2 Co 3 S 2 =Co 3 Sn 2 S 2 =SnCo 3/2 S exhibits giant anomalous Hall effects that exceed those of known materials by orders of magnitude. For this laboratory curiosity, a specific electronic topology has been discovered in the predicted half‐metal ferromagnetic S= 1 / 2 state that makes it a fascinating example of the novel group of magnetic Weyl semimetals. We present a chemical view on this compound that was little understood for a long time, but that is now also studied with respect to skyrmion lattices and thermoelectrics.
