摘要: Abstract Eight new diorganotin(IV) complexes of general formula R 2 Sn(DP) and [R Sn(DP)] O (DP = anion N -benzoyl- dl -alanylglycine; CH 3 , C H 5 n-C 4 9 8 17 ) have been prepared characterised by IR, 119m Sn Mossbauer spectroscopy. However, only two complexes, (DP) Sn(n-C were sufficiently soluble for NMR ( 1 13 C) studies. The : are monomeric with distorted trans -octahedral structures. dinuclear Sn-O-Sn bridges trigonal bipyramidal geometry about tin. In both cases the dipeptide acts as an O,O -bidentate ligand.
