A dinuclear double end-on azido bridged KM complex [Ni2L2(mu-(1),(1)-N-3)(2)(N-3)(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 (delta = -0.8(3) cm(-1)) were observed. DFT-BS calculations provided explanation of ferromagnetic exchange coupling in complex 1.
