Straightforward Donor Atom Switching: From P,C,P- to Various Y,C,Y-Pincer (Y = O, S, Se) Organotin(IV) Compounds and Cations.

A slight trend can also be described based on the bonding descriptors, namely the weakening of the Y → Sn interactions with the increasing number of phenyl substituents (WBI = 0.28, 0.25 and 0.23; H = −0.016, −0.012 and −0.009 for 1 O+ , 2 O+ and 3 O+ , respectively), however, these differences are less substantial than those observed for the dependency on the chalcogen centers.
