The synthesis and structural characterization of a samarium−dinitrogen complex supported by a calix[4]arene ligand in which the N−N bond distance has been stretched to 1.611(16) Å are described. The central μ3-η2:η2:η2-hydrazido tetraanion formed is bonded to three SmIII centers with an overall butterfly-type arrangement.
