Doubly phenoxo bridged heterometallic dinuclear Ni(II)-Na(I) complex [NiNaL(ClO4 )(CH3OH)], 1 (H2L = [(OCH3 )C6H3 (OH)CH=N(CH2CH)(CH3 )N=CH(OH)C6H3 (OCH3 )] has been synthesised and characterized by infrared, electronic spectra, electrochemistry and single crystal X-ray diffraction study. In complex 1, Ni(II) centre is distorted square-planar while the sodium(I) centre possesses pentagonal bipyramidal geometry. In the dimeric unit, the nickel and sodium atoms are held together by two distinct µ2 -phenoxo oxygen of the Schiff base ligand. The Ni-Na distance is 3.354(2) Å and the Ni-O-Na angles are found to be 107.4(5)º and 108.2(4)º. Density functional theory (DFT) calculation results for the complex 1 are also reported and compared with the experimental data.
