I have a compound that consists of a metal ion chelated by a linear organic structure with assorted moieties in aqueous medium. I'd like to dehydrate this mixture fully to get solid product, but heating is out of question due to unwanted repercussions on aforementioned "assorted moieties". If I lyophilize the compound, will it remain chelated or is there a risk of the metal ion unbinding?
I lyophilized my sample and redissolved a portion of it and confirmed chelation by verifying the presence of the absorption peak of the Lanthanide I was chelating and using Beer's Law.
Thanks for your help.
