Abstract

Solvothermal reaction of Co(OAc)₂·4H₂O with H₄L (H₄L = 2-((2-hydroxybenzylidene)amino)-2- hydroxymethylpropane-1,3-diol) in MeCN gave a mixed-valence pentanuclear cobalt complex [Co₅(HL)₂(H₂L)₂(OAc) ₂]·2.5H₂O. Crystal structural analysis revealed that two Co(iii) ions were linked to a central triangular Co(ii) core through HL^3- and H₂L^2- hydroxyl groups. Magnetic measurements showed interesting magnetic properties that were assigned to spin-orbital coupling and ferromagnetic exchange interactions.
