The organotin(II) salts [4‐ t Bu‐2,6‐{P(O)(O i Pr) 2 } 2 C 6 H 2 SnL]X ( 1 : X=B[3,5‐(CF 3 ) 2 C 6 H 3 )] 4 ; 2 : X=BPh 4 ) and [4‐ t Bu‐2,6‐{P(O)(O i Pr) 2 } 2 C 6 H 2 Sn(L)S] 2 (BPh 4 ) 2 ( 3 ) stabilized by two intra‐ and one intermolecular donor–acceptor interaction are reported. Compound 1 contains the first N‐heterocyclic carbene‐stabilized organotin(II) cation (see scheme; DMAP= p ‐Me 2 NC 5 H 4 N).
