N2 - A linear trinuclear Co(II) compound, [Co3(μ1,1-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 (μ1, 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 μ1, 1 - N3- nitrogen atoms and each terminal Co(II) is coordinated by two μ1, 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
