SnCU" ligand, interaction with

Quadrupole sphtting values, which generally indicate an imbalance in the p- or d-electron distribution around tin, only are found for tin(IV) compounds with quite different ligands or interactions, e.g. SnF4 has two short and four long Sn-F bonds and a A value of 1.66nuns while SnCU 2NMe3 has a A value of 0.
