Polyazide Chemistry. Preparation and Characterization of the First Binary Group 6 Azides, Mo(N3)6, W(N3)6, Mo(N3)7- and W(N3)7- and the NW(N3)4- and NMo(N3)4- Ions

Abstract

Whereas numerous binary transition-metal azido complexes have been reported,1 no binary Group 6 azides are known. Only a limited number of partially azide-substituted molybdenum and tungsten compounds have been reported. Furthermore, no heptaazido compounds have been described. Herein, we report the synthesis and characterization of the first binary Group 6 azides, Mo(N3)6, W(N3)6, Mo(N3)7-, and W(N3)7-. The last two ions represent the first examples of heptaazides. We also report the crystal structure of W(N3)6 and the controlled nitrogen loss from the heptaazido anions to give nitrido-teraazido anions. The NMo(N3)4- ion is already known but had been obtained by a different method.
