"Super hybrid tridentate ligands": 4-substituted-2-(1-butyl-1H-1,2,3-triazol-4-yl)-6-(1H-pyrazol-1-yl)pyridine ligands coordinated to Fe(ii) ions display above room temperature spin transitions.

A series of novel "super hybrid tridentate ligands" based on (2-(1-butyl-1H-1,2,3-triazol-4-yl)-6-(1H-pyrazol-1-yl)pyridine (tpp) derivatives were synthesized. Their Fe(ii) complexes display around (T(½) = 287 K) and above room temperature (T(½)≫ 375 K) spin transition temperatures.
