## Abstract The preparation of a family of dinuclear monocyclopentadienyl imidoniobium and ‐tantalum complexes was achieved by two different synthetic routes. The diimido complexes [{M(Cp′)Cl~2~}~2~(μ‐1,__i__‐NC~6~H~4~N)] [Cp′ = η^5^‐C~5~H~4~SiMe~3~, M = Nb, __i__ = 4 (1); Cp′ = η^5^‐C~5~H~4~SiMe~3
Two new 1,2,3,5-dithiadiazoles, [4-(4Ј-C 5 H 4 N)CN 2 S 2 ] (L 1 ) and [4-(3Ј-C 5 H 4 N)CN 2 S 2 ] (L 2 ), with different pyridyl groups at the 4-position were prepared. As Lewis bases, the dithiadiazoles reacted with Lewis acids via their pyridyl groups to form acid-base adducts with retention of t
## Abstract Ph~3~SnN(SiMe~3~)~2~ (1) was prepared in good yields by reaction of [{NaN(SiMe~3~)~2~}~2~·THF] (2) with Ph~3~SnF. Treatment of 1 with [H(OEt~2~)~2~][H~2~N{B(C~6~F~5~)~3~}~2~] (4) in dichloromethane afforded the stannylium cation [Ph~3~Sn(OEt~2~)][H~2~N{B(C~6~F~5~)~3~}~2~] (5), which was
