GRAPHICAL ABSTRACT

Abstract

The complexes [{(ArO)2PS2}2Mn(NC5H5)2] (1–4) [(Ar = 2,4-(CH3)2C6H3 (1), 2,5-(CH3)2C6H3 (2), 3,4-(CH3)2C6H3 (3), and 3,5-(CH3)2C6H3) (4)] have been isolated in aqueous medium and characterized by mass spectrometer, IR, magnetic susceptibility, and single crystal X-ray analyses. The complex [{(2,4-(CH3)2C6H3O)2PS2)}2Mn(NC5H5)2] (1) crystallizes in the monoclinic space group P21/n as a monomer with a basic core of the

four-membered ring [MnS4]. The octahedral sphere of the Mn atom is completed by donation from the nitrogen atoms of the two pyridine rings and four sulfur atoms of the dithio moiety. The thermal gravimetric analysis of the complex (1) revealed the end product as MnS. Screening of the ligands and complexes against the fungus Fusarium oxysporum has indicated potential antifungal activity.
