Abstract
Treatment of acetonitrile solutions of [{Fe(CO)2(cp)}2EX2](cp =η-C5H5; E = Ge, X = Br; E = Sn, X = Cl) with an excess of sodium azide affords the compounds [{Fe(CO)2(cp)}2E(N3)2](E = Ge or Sn). X-Ray crystallographic analyses of these compounds show that the Group 14 atom has a distorted-tetrahedral environment, with enlarged Fe–E–Fe angles and reduced N–E–N angles. Contributions from various resonance forms of the azide ligand are discussed, based on the solid-state data, and are compared to expectations based on solid-state and solution νasym.(N3) and ν(CO) i.r. stretching frequencies.Keywords
