Le mot de borane désigne des hydrures de bore, ainsi que des composés organiques de formule générale BH3R~ résultant de la substitution d'un ou de plusieurs atomes d'hydrogène du borane le plus simple BH. [...] Le bore, élément très léger, se distingue par une grande aptitude à former des dérivés hydrogénés de structures très variées : les atomes de bore peuvent en effet former des assemblages triangulaires (closoboranes), des chaînes ayant l'aspect d'un nid (nidoboranes) ou d'une toile d'araignée (arachnoboranes), et des dimères que l'on nomme conjonctoboranes. 3, record 1, French, - closo%2D
