Dialkyl (alkylene) dithiophosphate adducts of anhydrous stannous chloride: Synthesis, characterization, and biological activities

Dialkyl (alkylene) dithiophosphate adducts of stannous chloride were synthesized by the reaction of anhydrous tin(II) chloride (SnCl2) and dialkyl (alkylene) dithiophosphoric acid in a 1:1 molar ratio, under anhydrous reaction conditions, below 5 °C in a closed vessel. The newly synthesized adducts were characterized by physicochemical and spectroscopic techniques [FT-IR, NMR (1H, 31P, and 119Sn), and mass spectrometry]. Coordination modalities have indicated a donor-acceptor interaction between sulfur and tin(II) moieties, where tin(II) acts as a Lewis acid. The adducts were found to have significant antibacterial activity against Escherichia coli and Pseudomonas aeruginosa, and antifungal activity against Aspergillus niger and Candida albicans.

Synthesis, spectral characterization and antibacterial activity of O, O’-dialkyl and alkylene dithiophosphatogold (III)dichloride; crystal structure of [S2POCMe2CMe2O]AuCl2

O, O’-Dialkyl and alkylene dithiophosphatogold (III)dichloride complexes of the type [(RO)2PS2]AuCl2 and [S2POGO]AuCl2, where R = Et, nPr, iPr, iBu, Ph, cyclohexyl and cyclopentyl, where G = CMe2CMe2-, have been synthesized in 80-90% yields by reaction of the corresponding acid or sodium salts of the appropriate dithiophosphoric acids in 1:1 ratio with gold (III) chloride in dry dichloromethane at room temperature. The compounds have been characterized by elemental analyses, IR and (1H, l3C, and 31P) NMR. The crystal structure of [S2POCMe2CMe2O]AuCl2, was determined. These new complexes have shown their growth inhibiting potential against various bacterial strains with moderate to good activity.
