Synthesis, crystal structure, and antifungal activity of a newly synthesized polymeric mixed ligand complex of Zn(II) with 1,1-dithiolate and nitrogen donor<b>s</b>
<div><p>A new mixed ligand complex of Zn(II) with 1,1-dicyanoethylene-2,2-dithiolate [i-MNT<sup>2−</sup> = {S<sub>2</sub>C:C(CN)<sub>2</sub>}<sup>2−</sup>] and 1,3-diaminopropane as ligands has been synthesized and characterized on the basis of spectroscopy and single-crystal X-ray diffraction analysis. Spectroscopic studies and single-crystal X-ray diffraction analysis reveal that the zinc(II) complex is tetrahedral and adopts a 1,3-diaminopropane-assisted linear polymeric assembly. The molar conductance data of the complex in DMF solution show non-electrolytic nature. Biological screening effects of the complex <i>in vitro</i> have been tested against five fungi <i>Synchitrium endobioticum</i>, <i>Pyricularia oryzae</i>, <i>Helminthosporium oryzae</i>, <i>Candida albicans</i> (ATCC10231), and <i>Trichophyton mentagrophytes</i> by the disk diffusion method. A comparative study of inhibition zone values of the primary ligand K<sub>2</sub>i-MNT·H<sub>2</sub>O and its synthesized complex indicates that the complex exhibits a fungistatic antifungal activity whereas K<sub>2</sub>i-MNT·H<sub>2</sub>O does not affect <i>P. oryzae</i>.</p></div
