Supramolecular Lead(II) Azide Complex of 2,6-Diacetylpyridine Dihydrazone: Synthesis, Molecular Structure, and Biological Activity

Abstract

The complex of 2,6-diacetylpyridinedihydrazone (L) with lead(II) and azide has been characterized by elemental analyses, FTIR, and single-crystal X-ray analysis. The Pb(C<inf>9</inf>H<inf>13</inf>N<inf>11</inf>) (1) crystallized in the monoclinic space group C2/c. The coordination of 1 exhibits a gap around the lead(II), possibly occupied by a stereochemically active electron lone pair on lead(II) resulting in a hemidirected complex. Antimicrobial activity of the complex is higher than the free ligand. © 2009 Taylor & Francis.
