= non-chembox sections = Tetraboron tetrachloride is volatile boron subhalide, it has a hypercloso structure.

Structure and bonding
The boron atoms form a tetrahedral cage with chlorine decorating the vertices. Although the structure is similar to that of tetrahedrane, the bonding is not. Rather than having 2c-2e bonds along the edges of the tetrahedral cage, there are 3c-2e bonds spanning each of its faces.

Synthesis
Tetraboron tetrachloride is produced in small quantities by electrical discharge through boron trichloride or diboron tetrachloride.

Reactions
Tetraboron tetrachloride reacts with alkyl lithium compounds at room temperature to produce the corresponding mono, di, tri, and tetraalkylated tetraboron compounds. Cage degradation
