Change Type: Correction
Change Details: In the version of this News & Views originally published, in Fig. 1b, the compounds containing barium were labelled incorrectly. The two labels reading ‘4BaH’ should have read ‘2BaH<sub>2</sub>’, the three labels reading ‘Ba<sub>2</sub>NH’ should have read ‘BaNH’, and the label ‘BaH’ should have read ‘BaH<sub>2</sub>’. In the main text, ‘Ba<sub>2</sub>NH’ should have read ‘BaNH’, and ‘BaH’ should have read ‘BaH<sub>2</sub>’. These errors have now been corrected.
