| Abstract: | Eight new diorganotin(IV) complexes of general formula R2Sn(DP)2 and R2Sn(DP)]2O (DP = anion of N-benzoyl-dl-alanylglycine; R = CH3, C2H5, n-C4H9, n-C8H17) have been prepared and characterised by IR, and 119mSn Mössbauer spectroscopy. However, only two complexes, (DP)2Sn(n-C4H9)2 and (DP)2Sn(n-C8H17)2 were sufficiently soluble for NMR (1H and 13C) studies. The 2 : 1 complexes are monomeric with distorted trans-octahedral structures. The 1 : 1 complexes are dinuclear with Sn-O-Sn bridges and trigonal bipyramidal geometry about tin. In both cases the dipeptide acts as an O,O-bidentate ligand. |
