| Abstract: | Two octahedral complexes Ni(HL1)2](ClO4)2 (1) and Ni(HL2)2](ClO4)2 (2) and a square planar complex Ni(HL3)]ClO4 (3) have been prepared, where HL1 = 3-(2-amino-ethylimino)-butan-2-one oxime, HL2 = 3-(2-amino-propylimino)butan-2-one oxime] and H2L3 = 3-2-(3-hydroxy-1-methyl-but-2-enylideneamino)-1-methyl-ethylimino]-butan-2-one oxime. All the complexes have been characterized by elemental analyses, spectral studies and room temperature magnetic moment measurements. The molecular structures of all three compounds were elucidated on the basis of X-ray crystallography; complexes 1 and 2 are seen to be the mer isomers. |
