| Abstract: | The structural investigation of molecules in the vapor over neodymium tribromide was performed by synchronous gas-phase electron diffraction and mass spectrometric (GED/MS) experiments at 1110(10) K. Besides the monomeric molecules (NdBr3), a small amount (0.7%) of the dimer (Nd2Br6) was detected. For NdBr3, the thermal-average bond length rg(Nd–Br) of 2.675(6) Å was determined. The equilibrium structure was estimated to be planar (or nearly planar) with re(Nd–Br) of 2.659(7) Å. Three vibrational frequencies were estimated using the GED data:  1 = 193 cm–1, 2 = 35 cm–1, 4 = 41 cm–1. The structural parameters of Nd2Br6 could not be refined and were constrained at the estimated values during the analysis. |
