Zirconium silicon sulfide (ZrSiS) is a crystalline layered Dirac semi-metal compound of zirconium, silicon and sulfur. ^[1] Its crystals are made from planes of five single-atom layers of each element in the order S-Zr-Si-Zr-S, with the single element planes connected to their neighbors by van der Waals forces. ^{[1] [2]}

Semi-Dirac fermions were first observed within ZrSiS. ^{[3] [4]}
