Abstract: By laser ablation of NaBH_4 on a home-made instrument, four series of borane anions B_nH_m~- with formular of n=3k+1, m=5k+4; n=3k+2, m=5k+1; n=3k+2, m=5k+5; n=3k+3, m=5k+6 (k=0,1,2…) were observed at first time on recorded time-of-flight mass spectra with different ion intensities. From analysis of the mass spectra and calculate their possible topologies, a dragon-like structure was suggested for these new type of borane anions.

Key words: Borane, Bridged B-H bond, Laser plasma mass spectrometry
