Editing Boron hydride clusters (section)

==History==
The development of the borane hydride clusters resulted from pioneering work by [[Alfred Stock]], invented the glass vacuum line for their study.<ref>{{cite book |last= Stock |first=Alfred |year = 1933|title = The Hydrides of Boron and Silicon|publisher = Cornell University Press |location = New York}}</ref>  The structures of the boron hydride clusters were determined beginning in 1948 with the characterization of [[decaborane]]. [[William Nunn Lipscomb|William Lipscomb]] was awarded the [[Nobel Prize in Chemistry]] in 1976 for this and many subsequent [[X-ray crystallography|crystallographic investigations]]. These investigations revealed the prevalence of [[deltahedron|deltahedral]] structures, i.e., networks of triangular arrays of BH centers.

The bonding of the clusters ushered in [[Polyhedral skeletal electron pair theory]] and Wade's rules, which can be used to predict the structures of boranes.<ref>{{cite journal | doi = 10.1351/pac200375091315 | journal = [[Pure Appl.
