Extended Data Fig. 3: Diamond ATR-FTIR spectra of the decomposition products of 1Br8·26NH3 and 3Cl6·6NH3.
From: Complexes featuring a linear [N≡U≡N] core isoelectronic to the uranyl cation

a, b, Decomposition products of 1Br8·26NH3 (a) and 3Cl6·6NH3 (b) both after removal of liquid ammonia at room temperature. Uranyl impurities would result in a band at ~911–960 cm−1. The abbreviation rt stands for room temperature.
