Solvent-free mechanochemical synthesis of Zn(II), Cd(II), and Cu(II) complexes with 1-(4-methoxyphenyl)-4-(2-(1-(pyridin-2-yl)ethylidene)hydrazinyl)-1H-pyrrole-3-carbonitrile

Zn(II), Cd(II), and Cu(II) complexes with 1-(4-methoxyphenyl)-4-(2-(1-(pyridin-2-yl)ethylidene)hydrazinyl)-1H-pyrrole-3-carbonitrile (HP) were produced by using ball milling as a mechanochemical technique. The mode of chelation for the isolated complexes was illustrated by several spectroscopic techniques. Also, a computational study was estimated to prove the geometry of the isolated complexes by applying a density function theory method. In addition, its biological activity (antimicrobial and DNA binding) was evaluated.
