## Abstract The empirical Karplus‐type dependence of ^3^__J__(^119^Sn,^13^C) and ^3^__J__(^119^Sn,^1^H) couplings in organotin(IV) derivatives has been computationally validated by DFT methods both at the non‐relativistic and scalar ZORA relativistic level. A preliminary calibration of the computat

## Abstract The fundamental molecular aspects of trialkyltin compounds of the type R~3~SnY have been investigated in view of their applicability as ion‐selective components in solvent polymeric membranes. The interaction between these compounds and anions has been studied using ^119^Sn‐ and ^13^C‐N
The reaction of the 2,2-bis(organodichlorostannyl)propane [(Me 3 Si) 2 CH(Cl 2 )Sn] 2 CMe 2 (A) with the corresponding organotin oxide {[(Me 3 Si) 2 CH(O)Sn] 2 CMe 2 } 2 (B) does not provide the corresponding normally expected tetraorganodistannoxane {[(Me 3 Si) 2 CH(Cl)SnCMe 2 Sn(Cl)CH(SiMe 3 ) 2 ]
