The complex formation of [SnMe2]2+ ion with guanosine 5'-triphosphate (GTP), inosine 5'-triphosphate (ITP), cytidine 5'-triphosphate (CTP) and tripolyphosphate(5-) (tpp) has been investigated by means of potentiometric and calorimetric measurements at 25-degrees-C and I = 0.1 mol dm-3 (KNO3). On the basis of the thermodynamic parameters, bonding details have been inferred for the main nucleotide complex species, using tpp as reference. The thermodynamic data show that the nitrogen atom [N(1)] of the bases interacts with dimethyltin in the [SnMe2L] species of GTP and ITP only.
