A
family of heterospin complexes based on copper (II) hexafluoroacetylacetonate Cu(hfac)
2
with persistent nitronyl nitroxides L
R
was named as
breathing crystals
due to their ability to undergo reversible 'Single-Crystal-to-Single-Crystal' phase transformations.
Studying of these processes facilitates a detail investigation and understanding of solid dynamics. Phase exchange clusters 'Cu-O•-N'
or 'N-•O-Cu-O•-N'. This reorganization causes an appearance of magnetic anomalies on the dependence of the effective magnetic
moment vs temperature (or pressure) [1-5]. Our studies of more than one hundred complexes showed a wide variety of magnetic
anomalies caused by structural transformations and provide valuable information on the spin state in a heterospin solid.
