Both isomers of As 4 S 4 are molecular, in contrast to the other main sulfide of arsenic, orpiment (As 2 S 3), which is polymeric. In pararealgar, there are three kinds of As centres (and three kinds of S centres). The molecule has C s symmetry. In realgar, the four As (and four S) centres are equivalent and the molecule has D 2d symmetry. [6]
