De boranen leidden tot verschillende nieuwe technieken en ideeën in de chemie. The bis(diboranyl) is expected to have a lower energy at the Hartree-Fock method (HF) level.

Tetraborane (systematically named arachno-tetraborane(10)) was the first boron hydride compound to be classified by Stock and Messenez in 1912 and was first isolated by Alfred Stock.

According to its formula, B4H10, it is classified as an arachno-cluster and has a butterfly geometry, which can be rationalized by Wade's rules. Deze pagina is voor het laatst bewerkt op 10 aug 2020 om 20:34. De essentie van de geometrie van het cluster komt neer op een rangschikking van 7 booratomen in een pentagonale bipiramide, waarbij één hoekpunt met het grootste aantal directe buren (5) ontbreekt. Met behulp van deze regel, ook bekend als de regel van Wade, kan het type cluster closo-, nido-, enzovoort voorspeld worden. n+4 c) arachno - B nH n+6. [4]:3, The comparison of the diffraction data from X-ray diffraction and electron diffraction gave suspected bond lengths and angles: B1—B2 = 1.84 Å, B1—B3= 1.71 Å, B2—B1—B4= 98 ̊, B—H = 1.19 Å, B1—Hμ = 1.33 Å, B2—Hμ =1.43 Å.[4]:3.
