Synthesis and Crystal Structure Determination of a Nickel(II) Complex of an Acyclic Pentadentate (N(5)) Mono Schiff Base Ligand.

The asymmetrical tripodal tetraamine ligand N[(CH(2))(3)NH(2)](2)[(CH(2))(2)NH(2)] (ppe) was condensed with 2-acetylpyridine in the presence of nickel(II) ion. In ethanol-water solution the reaction stops after the first stage of condensation, and a new nickel(II) complex of an acyclic pentadentate...

Sumario:The asymmetrical tripodal tetraamine ligand N[(CH(2))(3)NH(2)](2)[(CH(2))(2)NH(2)] (ppe) was condensed with 2-acetylpyridine in the presence of nickel(II) ion. In ethanol-water solution the reaction stops after the first stage of condensation, and a new nickel(II) complex of an acyclic pentadentate (N(5)) mono Schiff base ligand was obtained. X-ray structure analysis of the resulting complex, [Ni(ppe-py)(H(2)O)](ClO(4))(2), indicates that condensation with 2-acetylpyridine is at the propylene chain of ppe. The geometry around the nickel ion is distorted octahedral in which the sixth co-ordination group is a solvent molecule.
