Abstract

A new cubane-based Co(ii) compound, [Co₁₂(5-PT)₆(CO₃)(N₃)₂(O)₄(CH₃O)₆(H₂O)₁₈] (1) (5-HPT = 5-phenyl-1H-tetrazole), was synthesized by reaction of 5-HPT, CoCl₂·6H₂O and NaN₃ in a methanol solution. In 1, a Co₁₂ cluster based on three identical Co₄O₂(ON)₂ cubane units bridged by a μ₆-carbonate ligand is linked by π-π stacking interactions between phenylene groups, forming a 3D supramolecular structure. Magnetic investigations indicate that compound 1 exhibits long-range ferromagnetic ordering at about 9 K. The cube-based Co₁₂ clusters with μ₆-CO₃^2- bridges are unprecedented.
