A tridentate NNO condensation product of 2-quinolinecarboxaldehyde and Girard's T reagent (HLC1) in the presence of azide ions coordinates with cobalt(II) giving mononuclear azido Co(II) complex [CoHL (N-3)(3)](1) as a main product and dinuclear end-on azido bridged Co(II) complex [Co2L2(mu-(1,1)-N-3)(2)(N-3)(2)] (2) in traces. Crystal structures of both complexes were determined. Variable temperature magnetic susceptibility measurement studies of complex I showed that Co(II) cation is in the low-spin state with t(2g)(6)e(g)(1) (S = 1/2) configuration. DFT-BS calculations for complex 2 anticipated ferromagnetic type interaction between paramagnetic centers (J = 53 cm(-1)).
