Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa).
The molecular structure conforms to C2 symmetry group. With the formula BnHn+6, it is classified as an arachno cluster. As such the boron positions match six of the boron positions in the closo-B8H2−
- LiB5H8 + 1/2 B2H6 → LiB6H11
- LiB6H11 + HCl → B6H12 + LiCl
