Abstract

The preparation and spectroscopic identification of the complexes NNBe(η²-N₂) and (NN)₂Be(η²-N₂) and the energetically higher lying isomers Be(NN)₂ and Be(NN)₃ are reported. NNBe(η²-N₂) and (NN)₂Be(η²-N₂) are the first examples of covalently side-on bonded N₂ adducts of a main-group element. The analysis of the electronic structure using modern methods of quantum chemistry suggests that NNBe(η²-N₂) and (NN)₂Be(η²-N₂) should be classified as π complexes rather than metalladiazirines.
