= non-chembox sections = closo-Azadodecaborane is a heteroborane/azaborane notable for having six-coordinate nitrogen.

Structure and bonding
Distorted icosahedral structure with exopolyhedral bonds to hydrogen and the bonds surrounding the nitrogen are shorter. NH contributes four electrons to the framework bonding something something has 2n+2 electrons contributing to bonding so it's a closo cluster something something Wade's rules something something.

Synthesis
nido-azaundecaborane(12) anion (NB10H12) and BH3
