AB  - Mnogi teorijski proračuni su pokazali da su litijumom dekorisni borani (BxHy) ili klasteri bora (Bn) potencijalni materijali za skladištenje vodonika. Pored toga, pokazalo se da klasteri litijumfluorida poboljšavaju kapacitet skladištenja vodonika bolje od samog litijuma. Međutim, broj eksperimentalnih studija je mnogo manji. Zbog toga je u ovom radu ispitivana mogućnost interakcije klastera litijuma ili litijumfluorida sa boranima, metodom laserske desorpcione/jonizacione masenespektrometrije (LDI MS). Preliminarni rezultati su pokazali da negativni mod LDI maseni spektri suspenzije LiF/B (1:3) u dejonizovanoj vodi sadrži Li2(BH18) - , LiF2(BH3) - , LiB2(BH3)2 - , LiF2LiB(BH4)2 - jone. Smanjenje sadržaja bora u LiF/B sistemu (1:1) rezultira malo izmenjenim masenim spektrom. Intenzitet Li2(BH18) - i LiF2(BH3) - opada, dok druga dva jona pokazuju blago izmenjen sastav: Li2F(B3H2) - i LiF2(BH5)3 - . Rezultati pokazuju da klasteri Li2 i “superhalogen” LiF2 mogu da interaguju sa boranima. U oba slučaja, najintenzivniji joni su bili kompleksi između „superhalogena“-LiF2 i borana.
AB  - Many theoretical calculations have shown that lithium decoration of borane (BxHy) or boron (Bn) clusters are potential materials for hydrogen storage. In addition, lithium fluoride clusters have been shown to improve hydrogen storage capacity better than lithium itself. However, the number of experimental studies is much smaller. Therefore, in this work, the possibility of interaction of lithium or lithium fluoride clusters with boranes was investigated by laser desorption/ionization mass spectrometry (LDI MS). The preliminary results have shown that the negative mode LDI mass spectra of the suspension of LiF/B (1:3) in deionized water include Li2(BH18) - , LiF2(BH3) - , LiB2(BH3)2 -  LiF2LiB(BH4)2 -  ions. The reducing the boron content in the LiF/B system (1:1) results in a little changed mass spectrum. The intensities of Li2(BH18) -  and LiF2(BH3) -  decrease, while two other ions show a slightly changed composition: Li2F(B3H2) -  and LiF2(BH5)3 - . The results show that the Li2 and “superhalogen” LiF2 clusters can interact with boranes. In both cases, the most intense ions were complexes between “superhalogen”-LiF2 and boranes.
