Ammonia reactivity with ferriotetrylenes: a structural snapshot of a highly dynamic process
Abstract
The reaction of ammonia with the ferriotetrylenes Ar′EFeCp(CO)2 (Cp = η5-C5H5; E = Sn(1), Pb(2); Ar′ = −C6H3-{C6H3-2,6-iPr2}2) afforded a product interpreted as either a tin amide hydride (3) or a tin ammonia complex, which has a very long Sn–N bond of 2.4289(3), and which readily regenerates 1 and NH3 under ambient conditions.
