Abstract: | Abstract Reactions of O-tolyldithiocarbonate ligands, (o-, m-, and p-CH3C6H4O)CS2Na, with anhydrous FeCl2 (1:2 molar ratio) and with FeCl3 (1:1 and 1:3 molar ratio) yielded the complexes {(CreO)CS2}2Fe] and {(CreO)CS2}nFeCl3–n] (Cre = o-, m-, and p-CH3C6H4; n = 1 and 3), respectively. These complexes were reacted with nitrogen and phosphorus donor ligands in dichloromethane, which afforded the adducts corresponded to {(CreO)CS2}2Fe.xL] and (CreO)CS2FeCl2.xL] {x = 1, L = N2C12H8; x = 2, L = NC5H5, P(C6H5)3}. Elemental analyses and IR, UV-visible, and mass spectroscopic and magnetic studies indicated bidentate mode of bonding by dithiocarbonate ligands leading to sixcoordination around the iron atom as a consequence of Fe…Fe interaction in the complexes {(CreO)CS2}2Fe] and (CreO)CS2FeCl2]. The complexes exhibited antifungal activity. The fungicidal activity of the complexes has been tested by poisoned food technique using fungi Fusarium sp.
