Abstract

Blended ligand edifices of Cu (II) with salen type ligands, in particular N, Nãšâ¹-bis(salicylidene)- 1,2-ethylenediamine (salen) and N, Nãšâ¹-bis(salicylidene)- 1,2-pheneylenediamine (salophen) as essential ligands and pyrrolidine dithiocarbamate (pdtc) as an optional ligand were ready. The primary portrayal of the blended buildings was done by means of insightful as well as different ghastly examinations. The got results support that stoichiometry of the mononuclear blended ligand edifices can be addressed as NH4[Cu (II)- Schiff base(L)- pdtc (B)] and both H2L and (B) ligands can go about as tetra and bidentates separately. Moreover, both the schiff bases and the optional pdtc ligands tie with copper (II) particle to fabricate a steady six, five, six and four membered chelate rings with an octahedral calculation. The mass spectral data confirms the monomeric structure of the metal complexes while the study of the conductivity measurement indicated the 1:1 electrolyte nature of the complexes. The free Salen type ligands and their mixed copper (II) complexes have been tested for their antibacterial activity by using disc diffusion method and the results discussed.
