Here is an example that is is not cryocongelation but spacegroup change
upon cooling :
Garavito RM, Jenkins J, Jansonius JN, Karlsson R, Rosenbusch JP. X-ray
diffraction analysis of matrix porin, an integral membrane protein from
Escherichia coli outer membranes. J Mol Biol. 1983 Feb 25;164(2):313-27.
PubMed PMID: 6302273.
