The complex formation of dimethyltin(IV) ([SnMe(2)](2+)) with alanine, phenylalanine, triptophane and valine has been investigated by means of potentiometry at 25 degrees C and I = 0.1 mol dm(-3) (KNO3). The selection of the models and the calculation of stability constants have been performed collecting a large amount of data points and using three different computer programs. This procedure has made it possible to detect the species forming in low percentages. A comparison with monodentate and bidentate systems previously studied gives an indication as to the number and the nature of the donor atoms involved in the coordination.

Abstract
The complex formation of dimethyltin(IV) ([SnMe(2)](2+)) with alanine, phenylalanine, triptophane and valine has been investigated by means of potentiometry at 25 degrees C and I = 0.1 mol dm(-3) (KNO3). The selection of the models and the calculation of stability constants have been performed collecting a large amount of data points and using three different computer programs. This procedure has made it possible to detect the species forming in low percentages. A comparison with monodentate and bidentate systems previously studied gives an indication as to the number and the nature of the donor atoms involved in the coordination.File in questo prodotto:
