Synthesis, Crystal Structure and Biological Activity of the Nickel(II) Complex of 2,6-Diacetylpyridinedihydrazone

Abstract

A complex of NiII with 2,6-diacetylpyridinedihydrazone (L) towards nickel(II) has been prepared and characterized by means of elemental analyses, IR, electronic spectra and single crystal X-ray analyses. [NiL <inf>2</inf>](NO<inf>3</inf>) was crystallized in the tetragonal space group P-4 21 c. The complex exhibits the expected coordination sphere with six nitrogen atoms coordinated to the central NiII with a deformation from pseudo-octahedral geometry. Antimicrobial activities of the ligand and its complex were investigated. © 2007 Springer.
