| Abstract: | The reaction of equimolar quantities of Ni(ClO4)2.6H2O, NaN3 and a deprotonated tetradentate bridging N-donor ligand, [L2]-, HL2=2-[2-(pyridylamino)phenylazo]pyridine, produces a novel di-metallic Ni2-complex having double [NAr2] bridges. The complex has been isolated and suitable X-ray quality crystals grown through slow evaporation of the concentrated acetonitrile solution of the compound. The complex has been characterized fully using its physicochemical properties as well as single crystal X-ray data analysis. Its structure reveals that the two deprotonated secondary amine nitrogens, viz. N(4) and N(9) of two [L2]- bind two Ni(II) centers simultaneously forming planar Ni2N2 arrangement. The complex is paramagnetic and its solution exhibits blue colour, which shows charge-transfer transitions near 600 nm. |
