Organotin(IV) trifluoromethanesulfonates chemistry: Isolation and characterization of a new di-n-butyl derivative presenting a Sn3O3 core

► [n-Bu2Sn(OH)(H2O)(CF3SO3)]2 reacts with a mixture of anthracene and phenazine. ► A new di-n-butyltin(IV) trifluoromethanesulfonate salt was isolated. ► The tin(IV) dication is a trinuclear cluster exhibiting a planar Sn3O3 core. ► Concomitant crystallization of phenazinium trifluoromethanesulfonate salts occurred. ► Sandwich-type edifices via slipped parallel π-π aromatic interactions are observed.
