Seeds obtained from a hydrated polymorph permit crystallisation of an elusive anhydrous organometallic zwitterion

Abstract

Single crystals of the anhydrous polymorphic modification of the organometallic zwitterion [Co^III(η⁵-C₅H₄CO₂H)(η⁵-C₅H₄CO₂)] can only be obtained by seeding the solution with seeds prepared after stepwise dehydration and consequent phase transition at 506 K of the hydrated material [Co^III(η⁵-C₅H₄CO₂H)(η⁵-C₅H₄CO₂)]·3H₂O.
