Boron hydrides. The boron hydrides are called boranes with general formula Bn Hn+4 and Bn Hn+6. The well known boron hydrides are: diborane (B2H6), tetraborane (B4H10), pentabâ¦orane (B5H9), hexaborane (B6H10), nonaborane (B9H15), and decaborane (B10H16). The boron does not combine with hydrogen to form boron hydrides.
