Kanatzidisite is a mineral of the sulfosalt class with a composition of [BiSbS₃][Te₂]. It crystallizes in the monoclinic crystal system (space group: P2₁/m) with lattice constants a = 4.0021(5) Å, b = 3.9963(5) Å, c = 21.1009(10) Å and β = 95.392(3)°.^[1] Its structure features very unusual van der Waals heterolayers of alternating BiSbS₃ double layers and atomically thin distorted [Te₂] square-net. Based on its calculated band structure, kanatzidisite may exhibit topological features characteristic of a Dirac semimetal.^[2]^[3] Associated minerals are arsenopyrite, pyrite, marcasite, sphalerite, chalcopyrite, gold, bismuth, bismuthinite, ikunolite, jonassonite, jaszczakite ([(Bi,Pb)₃S₃][AuS₂]) and cosalite in a quartz matrix.^[1] A mineral specimen was detected by Luca Bindi and is currently stored in the Museum of Natural History of the University of Florence in Italy. The name of kanatzidisite is after Mercouri Kanatzidis, a distinguished chemist who holds the position of Professor of Chemistry at Northwestern University and Senior Scientist at Argonne National Laboratory.^[4]
