Whenever I searched "$\ce{B12H12}$ Borane", I can't seem to find anything, and get met with only the dianion of $\ce{B12H12}$. Why doesn't $\ce{B12H12}$ exist on its own?

    The general formulae of boranes are $\ce{B_nH_{n+4}}$ and $\ce{B_nH_{n+6}}$. – AChem Nov 26 '20 at 22:13

    Apparently polymeric BH exists - perhaps B12H12 could be an intermediate that further polymerises. It's just too unsaturated. – Mithoron Nov 26 '20 at 22:46

    Hypercloso boranes are generally unstable. However, its derivates are known. For mre details see this: https://onlinelibrary.wiley.com/doi/10.1002/1521-3773(20010504)40:9%3C1664::AID-ANIE16640%3E3.0.CO;2-O – Nilay Ghosh Nov 27 '20 at 03:51
