The crystal structures and spectroscopic properties of both E- and Z-isomers of N'-(1H-imidazol-4-ylmethylene)-picolinohydrazide (H2Lim) were investigated. In addition, an aerobic reaction of H2Lim with Co(BF4)2 in methanol afforded a mononuclear cobalt(III) complex, [Co(Z-HLim)2]BF4 (1) bearing tridentate hydrazonate ligands, and a dinuclear complex of [Co2(μ-E-HLim)3](BF4)3 (2), where the hydrazonate bridged two CoIII centers in the μ-κ2N,N': κ2N'',N''' mode to form an C3-symmetry triple helicate complex.
