Synthesis and characterization of some metal chelates derived from N, N`-bis[(ethylcarbamothioyl)amino] propanediamide (EAP; L) by tribochemical reaction and its biological application

Document Type : Original Article

Abstract

New metal chelates derived from EAP were synthesized in the solid state and in the absence of solvents by tribochemical reaction. The isolated ligands and metal chelates are characterized by chemical, spectral and magnetic methods. IR data suggest that the ligand (EAP) coordinates to two and/or three metal ions via the enolized CO, SH and the azomethine (C=N) groups with displacement of hydrogen atoms from the first two groups. The geometries of the isolated solid chelates were illustrated by spectral and magnetic data and confirmed by material studio program. DFT calculations suggest the most suitable geometry as well as the stability of the complexes. Some chelates were tested against anti-oxidant.
