Side-On Bonded Beryllium Dinitrogen Complexes.


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