The reactions of [ArE(Cl)]2 (E = Ge, Sn; Ar
= −C6H3-2,6-(C6H3-2,6-iPr2)2 (ArPri4), −C6H3-2,6-(C6H2-2,4,6-iPr3)2 (ArPri6)) with K[(η5-C5H5)Fe(CO)2] afforded the
deep green
ferriogermylenes ArGeFe(η5-C5H5)(CO)2 (Ar = ArPri4 (1), ArPri6 (2)) and the ferriostannylenes
ArSnFe(η5-C5H5)(CO)2 (Ar = ArPri4 (3), ArPri6 (4)), respectively. Complexes 1–4 were characterized by NMR, UV–vis,
and IR spectroscopy, as well as by X-ray crystallography. The solid-state
structures of 1–4 feature two-coordinate
Ge or Sn atoms with bent C–E–Fe (E = Ge, Sn) geometries.
Although germylenes 1 and 2 remain intact
upon heating or UV irradiation, stannylenes 3 and 4 were shown to eliminate one carbonyl group upon exposure
to UV light, affording the brown dimeric species {ArSnFe(η5-C5H5)(CO)}2 (Ar = ArPri4 (5), ArPri6 (6)), respectively.
