摘要

Laser-ablated Mo and W atoms react with N_2 in excess nitrogen and argon to form the metal nitrides, MN, and ligated complexes, (NN)_xMN, the metal dinitrides, NMN, and ligated complexes, (NN)_xMN_2, and several complexes M(NN)_x leading up to the octahedral species with x = 6. On the basis of the resolution of natural abundance Mo isotopes and ~(15)N substitution, the open, bent NMoN molecule valence angle is 106 +- 3 deg. The dinitride molecules are formed both by direct insertion of metastable metal atoms into dinitrogen and by the addition of atomic nitrogen to the mononitride molecule.
