Short summary

The As₄S₆ molecule was missing in the reported structures of crystalline As chalcogenides. Here we report the first occurrence of the As₄S₆ molecule together with the other known As₄S_n (n = 3, 4, 5) molecules randomly replacing each other in the crystalline structure of a new monoclinic product obtained by the light-induced alteration of the mineral alacranite, As₈S₉.
