Deskripsi
<p>Reactions between [M(L)]<sup>2+</sup> [M= Cu(II), Co(II), Cd(II), Zn(II) and Ni(II)] and [Fe(CN)6]<sup>3-</sup> give rise to cyano-bridged assembled bimetallic complexes. Their structures have been proposed by elemental analyses, IR, UV-VIS and <sup>13</sup>C NMR spectra, conductance and magnetic measurements studies. The structure is supposed to consist of zigzag chains formed by an alternate array of the cations and [Fe(CN)<sub>6</sub>]<sup>3-</sup> anion having neutral Ni<sub>3</sub>Fe<sub>2</sub> units. Each hexacyanoferrate(III) ion connects three nickel(II) ions using three cis CN<sup>-</sup> groups and the remaining CN<sup>-</sup> groups are terminal. The bridging cyanide ligands co-ordinate to the metal ion in a trans fashion forming trans-ML(CN)<sub>2</sub> moieties. Antibacterial activity of some of the prepared complexes has also been investigated against three human pathogen bacteria.</p>
