Diborane - Wikipedia
The structure of diborane has D 2h symmetry. Four hydrides are terminal, while two bridge between the boron centers. The lengths of the B–H bridge bonds and the B–H terminal bonds are 1.33 and 1.19 Å respectively. This difference in bond lengths reflects the difference in their strengths, the B–H bridge bonds being relatively weaker.
structure as ethene. There is p-electron density above and below the plane in which all six atoms lie (just like ethene) and so if we imagine embedding a proton in each face of this flat molecule, we balance the charge and arrive at the correct geometric structure.

Diborane played a key role in the development of our understanding of the bonding in electron deficient compounds. Although it was first isolated and characterized by Stock in 1912, 1 and recognized from its molecular formula as posing something of a valence problem, the distribution of its valence electrons in the molecule could not of course ...
Borane | Description, Structure, & Facts | Britannica
The simplest isolable borane is B 2 H 6, diborane(6). (The Arabic numeral in parentheses indicates the number of hydrogen atoms.) It is one of the most extensively studied and most synthetically useful chemical intermediates.
15.4.1: Boranes - Chemistry LibreTexts
Boranes are compounds consisting of boron and hydrogen.The most basic example is diborane (\(\ce{B2H6}\)), all boranes are electron-deficient compounds. For \(\ce{B2H6}\) usually 14 electrons are needed to form 2c,2e-bonds, but only 12 valence electrons are present.
Diborane, B2H6, is a colorless gas forming explosive mixtures with air. Diborane is endothermic with H. f = 36 kJ/mol Despite this thermodynamic stability, diborane is kinetically not so reactive but takes place in many reactions involving loss of H2 Industrial synthesis: 8 BF3 + 6 …
