A dinuclear double end-on azido bridged Ni(II) complex [Ni2L2(μ-1,1-N3)2(N3)2] (1) with the condensation product of 2-quinolinecarboxaldehyde and trimethylammonium acetohydrazide chloride (Girard’s T reagent) (HLCl) has been synthesized and characterized by elemental analysis, IR spectroscopy, single-crystal X-ray diffraction, magnetic measurements and DFT studies. In complex 1 intra-dimer ferromagnetic coupling between Ni2+ ions (J = +12.0(2) cm−1) and inter-dimer antiferromagnetic interaction (δ = −0.8(3) cm−1) were observed. DFT-BS calculations provided explanation of ferromagnetic exchange coupling in complex 1.
