Consecutive substitution reactions of arsenic(III)chloride with sodium salts of various oximes and morpholinedithiocarbamate (morphdtc) were carried out in 1:2:1 stoichiometry to obtain six new arsenic(III) mixed derivatives of the type: [(R)(R1)C = NO]2Sb[S2CN(CH2CH2)2O] [where R is –C6H5, R1 = –CH3 (1); R = –C6H4CH3, R1 = –CH3 (2); R = –C6H4Cl, R1 = –CH3 (3); R = –C6H4Br, R1 = –CH3 (4); R = –C6H4OH, R1 = –H (5); R(R1)C =  (6)]. These derivatives are characterized by elemental and physicochemical analyses and the tentative distorted trigonalbipyramidal geometry around arsenic assigned using spectral data of infrared (1H, 13C) nuclear magnetic resonance and liquid chromatography‐mass. Powder X‐ray diffraction study revealed their nanoranged particle size to be approximately 40 nm and crystalline nature. These derivatives examined against microbes and results revealed that these derivatives expressed more antifungal potential than antibacterial. The antioxidant activity was carried out by ferric reducing ability of plasma assay, and the cytotoxic study was performed in 3T3 fibroblast cell lines by tetrazolium‐based colorimetric assay.
