Complexes of organometallic compounds. XLVII. Synthesis of dimethyltin(IV) adenosinate and its characterization by Mössbauer and infrared spectroscopy

Syntheses, Mössbauer and infrared spectroscopic investigations on tin(II) chloride adducts with purine and pyrimidine bases and nucleosides

Abstract The synthesis of two types of tin(II) complex SnCl2·L·CH3OH (L = adenosine, cytidine and inosine) and SnCl2·L2·CH3OH (L = adenine and cytosine) are described. The complexes are characterised by their infrared and 119Sn Mossbauer data. The Mossbauer shift data suggest that the bonds between tin(II) chloride and the donor atoms of the ligands are relatively weak.

Synthesis of diorganotin(IV) complexes with nucleosides and their Characterization by Mössbauer and infrared spectroscopy

Abstract A number of new complexes of R 2 Sn IV with adenosine, guanosine, inosine, cytidine and uridine were synthesized by reaction of ribonucleosides with diorganotin oxide in hot methanol. The complexes were characterized by infrared and 119 Sn Mossbauer spectroscopy as O(2′), O(3′) (diorganostannylene) nucleosides; the occurence of dimers with three-co-ordinate oxygen atoms is inferred on the basis of spectroscopic data.
