Synthesis, crystal structure and biological activity of the nickel(II) complex of 2,6-diacetylpyridinedihydrazone

Abstract

A complex of Ni (II) 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. [NiL2](NO3), 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. The Antimicrobial activities of the ligand and its complex were investigated.
