Structure/terminology confusion[edit]
The Olsen-1968 ref talks about two geometric isomers identified as "n" and "i", but the Londesborough-2012 ref talks about "syn" and "anti" isomers. From their diagrams and descriptions, these seem like the same pair of isomers. Borane chemistry isn't my specialty, so I don't know if there is some other difference I'm not seeing, or if terminology for this class was changed in in the intervening years.

- Olsen mentions that the two have been "characterized by X-ray diffraction studies", citing:

- That doi:10.1021/ja00895a046 has nice perspective diagrams comparing them. DMacks (talk) 16:22, 2 July 2014 (UTC)
