On the nature of bonding in N-5(+) ion

The structure of recently synthetized N-5(+) ion was analyzed using two rec ently proposed methodologies, namely the generalized population analysis an d the Fermi hole analysis. It has been shown that as a remnant of its synth etic precursor, the azide ion namely, the molecule contains the system of t wo partially perturbed three-center four-electron (3c-4e) bonds localized i n the corresponding terminal NNN fragments. This structural assignment agre es with recently proposed analyses based on other methodologies. (C) 2001 E lsevier Science BN. All rights reserved.
