Abstract: | A new polymorph of pergolide mesylate or 8β‐[(methylsulfanyl)methyl]‐6‐propylergoline methanesulfonate, C19H27N2S+·CH3SO3−, is reported. Pergolide mesylate form II crystallizes in the trigonal system, which is unique for ergot derivatives. Although the hydrogen‐bond system in form II differs completely from that in form I, the conformation of the pergolide moiety in various related structures is very similar. |
