AbstractMonometallic complexes of Cu(II) of type [Cu(C12H14N4XCl)]Cl2 (where X=Cl or F) were synthesized by treating CuCl2 with the two diamines 4-chloro 1,2-phenylenediamine and 4-fluoro 1,2-phenylenediamine separately in 1:2 stiochiometric proportions. These synthesized complexes were further utilized for the preparation of heterobimetallic complexes of copper with organosilicon dichlorides (R2SiCl2) [where R=C6H5 or CH3] of the type [Cu(C36H30N4Si2XCl3)] and [Cu(C16H22N4Si2XCl3)] (where X=Cl or F). All the complexes were characterized by elemental analysis, conductance measurement, electronic spectra, IR, ESR, mass spectra and X-ray powder diffraction studies. These complexes were then evaluated for their antimicrobial efficacy with Bavistin and Streptomycin used as standards. The complexes were also tested for their plant growth regulating activity against gram plant and the results attained were quite promising.
