Abstract
Monomeric [Cu(DCA–OEt)2] and polymeric [Cu(DCA)2(DMF)2]n complexes (where DCA is dicyanamide, DCA–OEt is in situ formed ligand, and DMF is dimetylformamide) derived from sodium dicyanamide are synthesized and their structures are characterised by spectroscopic and analytical methods. Molecular structures of the complexes are determined by single crystal X-ray diffraction studies. In the structure of the polymeric complex [Cu(DCA)2(DMF)2]n, the DCA anions are bridges between Cu(II) ions through the terminal nitrile N atoms, forming a 1D ladder-like coordination polymer chains. The DCA–OEt ligand in the monomeric [Cu(DCA–OEt)2] complex is formed by the nucleophilic addition of ethanol to the DCA nitrile groups, resulting in a bidentate chelate ligand. The antibacterial activity of the structurally characterised complexes are evaluated by by agar-well diffusion. The complexes exhibit a comparable antibacterial activity against some bacteria to the standart antibiotics (amikacin and gentamicin).
