- Abstract
Two new Schiff base complexes, [Ni2(HL)2(l1,3-N3)]ClO4H2O (1) and [Co(L)(N3)] (2) where L = 2,20-{(methylimino)bis[propane-3,1-diylnitrilomethylylidene]}diphenolate ion, have been synthesized bythe reaction of equimolar amounts of nickel(II) or cobalt(II) perchlorate with the pentadentate Schiff baseligand (H2L) in presence of azide ion. The complexes have been characterized by microanalytical, spectroscopic,single crystal X-ray diffraction and other physicochemical studies. Structural studies reveal that 1is an end-to-end azido-bridged binuclear complex in which each nickel(II) adopts irregular octahedralgeometry. In contrast, 2 is a mononuclear octahedral cobalt(III) complex containing the azide ion inone of its apical positions. Low temperature magnetic measurements on 1 indicate noticeable intradimerferromagnetic interactions.
