Abstract

A linear trinuclear Co(II) compound, [Co₃(μ_1,1-N₃)₄ (N₃)₂(H₂O)₂(bpbp)₂] · 2H₂O (1, bpbp = 3,3′-bis-Dimethylamino-1,1′-pyridine-2,6-diyl-bispropenone), is reported. The central Co(II) ion is bridged to Co(II) ions on both sides by four end-on azide (μ_{1, 1} - N₃^-) ligands resulting in a centrosymmetric trimer with adjacent Co⋯Co distance of 3.233 Å. Each Co(II) ion possesses distorted octahedral geometry, the central one is coordinated by two aqua ligands and four μ_{1, 1} - N₃^- nitrogen atoms and each terminal Co(II) is coordinated by two μ_{1, 1} - N₃^- nitrogen atoms, one terminal N₃^- nitrogen atom and capped by terminal tridentate bpbp ligand. Variable temperature magnetic studies indicate ferromagnetic coupling between adjacent Co(II) ions within the trimer. Crown
