Synthesis, Spectroscopic, DNA Binding, and Antimicrobial Studies on bis (1-amidino-O-alkylurea) Cu(II) Tartrate Complexes Where Alkyl = Methyl, Ethyl, n-Propyl, n-, or Iso-Butyl

Five New Cu(II) complexes, [bis(1-amidino-O-alkylurea) Cu(II)tartrate], where alkyl= methyl (1), ethyl (2), n-propyl (3), n-butyl (4), or iso-butyl (5) have been synthesized and characterized. The electron paramagnetic resonance spectra of complexes 1 and 2 showed features of mononuclear species whereas complexes 3, 4, and 5 in frozen DMSO solution show the existence of mononuclear and binuclear species in these complexes. Complexes crystallize...
