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