Abstract

Abstract: The preparation and spectroscopic identification of the complexes NNBe(η 2 ‐N2 ) and (NN)2 Be(η 2 ‐N2 ) and the energetically higher lying isomers Be(NN)2 and Be(NN)3 are reported. NNBe(η 2 ‐N2 ) and (NN)2 Be(η 2 ‐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(η 2 ‐N2 ) and (NN)2 Be(η 2 ‐N2 ) should be classified as π complexes rather than metalladiazirines.
