Co^II Complexes with a Tripyridine Ligand, Containing a 2,6-Di-tert-butylphenolic Fragment: Synthesis, Structure, and Formation of Stable Radicals.

ABSTRACT: Interaction of a tripyridine ligand bearing a 2,6-di-tert-butylphenolic fragment (L, 2,6-di-tert-butyl-4-(3,5-bis(4-pyridyl)pyridyl)phenol) with Co^II pivalate or chloride led to the formation of one-dimensional coordination polymers [Co(L)Cl₂] _n ·nEtOH (1) and [Co₃(L)₂(OH)(Piv)₅] _n (2) or a trinuclear complex Co₃(H₂O)₄(L)₂Cl₆ (3) (Piv^- = pivalate). Chemical oxidation of L and 1-3 by PbO₂ or K₃[Fe(CN)₆], as well as exposure of L (in solution or solid state) and 2 (in solid state) to UV irradiation, led to the formation of free radicals with <
