Summary

11-(4H-1,2,4-Triazol-4-yl)-undecylmethacrylate (1), a new ligand for Fe(II) spin-crossover (SCO) complexes containing a polymerizable group, was synthesized and characterized. The complex [Fe • 1 3](BF4)2 (2) was obtained by reaction of 1 with Fe(BF4)2 • 6H2O (molar ratio 1/Fe(II) = 3/l) in THF. Complex 2 showed a gradual spin-crossover between 80 and 230 K. The methacrylate units in the ligands of complex 2 could be oligomerized radically in solution (initiator: azoisobutyronitrile) without loss of the spin-crossover behaviour.

Dedicated to Prof. Dr. K. Hummel on the occasion of his 70th birthday
