Spectroscopic Characterisation And Biological Applications Of Organotin(Iv) Derivatives Of 3-(N-Naphthylaminocarbonyl)-2-Propenoic Acid, Sajjad Ahmad, Moazzam H. Bhatti, Saqib Ali, Fiaz Ahmed
Turkish Journal of Chemistry
In an effort to develop new organotin materials for investigation and biocidal evaluation, a series of compounds with the general formula R_{4 - n}SnL_n (where R = CH_3, n-C_4H_9, C_6H_5, C_6H_5CH_2 and L = 3-(N-naphthylaminocarbonyl)-2-propenoic acid) were synthesised, and characterised by elemental analysis, IR, multinuclear (^1H, ^{13}C and ^{119}Sn) NMR, ^{119m}Sn Mössbauer spectroscopy and mass spectrometry. The biological activity of these compounds against various bacteria and fungi was investigated. All of the compounds were active against the fungi tested with a few exceptions. These compounds also showed significant antibacterial activity. LD_{50} data show that the investigated compounds have significant toxicity.

Turkish Journal of Chemistry
A series of five-coordinated germanium-substituted tricyclohexylantimony dipropionates have been synthesized and characterized by different instrumental techniques, such as elemental analyses, FT-IR, multinuclear NMR (^1H, ^{13}C) and mass spectrometry. These compounds have also been screened against different microbes and they showed good activity against different bacteria that was comparable to the reference drugs. The crystal structure of the precursor (C_6H_{11})_3SbBr_2 is reported here, which showed that the antimony atom in an asymmetric unit exists in trigonal bipyramidal geometry, having space group C2/c with the monoclinic crystal system.
