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.

There are a couple of papers...
Acta Cryst. (2010). F66, 346-351
Crystallization and X-ray diffraction studies of cellobiose phosphorylase from
Cellulomonas uda
The space group was originally P21. During collection the crystal moved out of
the beam (and possibly the cyrostream). Upon recentering, the space group was
found to be P212121
Acta Cryst. (1998). D54, 448-450
Crystallization and preliminary X-ray analysis of thiaminase I from Bacillus
thiaminolyticus: space group change upon freezing of crystals
At room temperature the space group was P212121 but upon freezing the space
group changes to P21212
Hope this helps.
