Abstract: The reaction of bisnitronylnitroxide with a diacetylene bridging group and diazomethane leads to the modification of the initial substrate while preserving its paramagnetic centers. As a result, new nitronylnitroxide biradicals containing a bispyrazolyl fragment were prepared. Molecular and crystal structures of the biradicals are determined by single crystal XRD.
