Abstract

The microwave spectra of three isotopic Ge species of germyl azide, GeH3N3, have been assigned. The splittings due to internal rotation of the germyl group have been analyzed yielding a threefold barrier of 86.6(1) cm-1. An electric dipole moment of 2.58(2) D has been determined from the Stark effect. The following refined structural parameters have been obtained with a fixed and slightly bent azide group: r(GeN) = 1.866(12) Å, r(GeH) = 1.497(8) Å, α(GeNN) = 115.9(14)°,α(HGeH) = 112.2(10)° and a tilt of the symmetric germyl group of 4.0° away from the azide group.
