“…Methylene groups carbon signals, directly attached to oxygen and nitrogen atoms have appeared at δ50 and δ64, respectively. On the other hand, in the signal of >C=N imine carbon non‐notable shift in derivatives as compared to free oxime moieties signifying the As−O bond formation [37] . Signals for phenyl carbon bound to arsenic metal exhibited in the range δ128.4–139.5.…”

[37] Signals for phenyl carbon bound to arsenic metal exhibited in the range δ128.4-139.5. For the carbon of phenyl rings which attached to arsenic atom the altered δ ' chemical shift [41] and σR 0 Hammett-Taft constant [42] were respectively determined via the equations δ ' = δC p -δC m (where δC p and δC m are chemical shift of para-and meta-carbons of aromatic ring bound towards arsenic) and δ ' = 23.06 σR 0 .…”

“…Two bands were identified at 3090 cm À 1 and 2970 cm À and were assigned corresponding to aromatic and alkyl v(CÀ H) groups. A band due to C=C stretching vibration was observed at 1565-1670 cm À 1 [8,37,38] Scheme 1. Triphenylarsenic(V)mixed ligand derivatives synthesis: (i) substitution of Ph 3 AsBr 2 by sodium salt of oxime (ii) further substitution of (R 1 )(R 2 )C=NOÀ As(Ph) 3 Br by MorphdtcNa.…”

C=CÀ CH 2 À (CH 2 ) 3 À CH 2 (1 F)] by consecutive substitution of Ph 3 AsBr 2 with sodium salt of substituted oximes and morpholinedithiocarbamate in equimolar proportion. Distorted octahedral geometry was proposed around the arsenic atom, for these derivatives. Nano ranged particle size ∼ 35 nm with crystalline nature was obtained by powder XRD study for these deriva-tives. The derivatives were examined for bacteria and fungi which exhibited higher antifungal capability than antibacterial. Cytotoxic and antioxidant activities were performed through MTT test in 3T 3 fibroblast cell lines and by FRAP assay, respectively for these derivatives. Amongst six triphenylarsenic(V) mixed ligand derivatives, 1 A, 1 B and 1 C were observed non-noxious (cell viability > 50 % even at 500 μg/mL) in nature and 1 D, 1 E and 1 F were poisonous to 3T 3 fibroblast cell lines. Structural-Activity relationship for antimicrobial and antioxidant activity amongst six derivatives 1 A-1 F was explored.

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.
