Chemistry - CHEMICAL BONDING Question with Solution | TestHub

The given diagram represents a dimeric structure formed by two edge-sharing tetrahedra.

In Al₂Cl₆, two aluminum atoms share an edge through two bridging chlorine atoms using coordinate covalent bonds.

In B₂H₆ (Diborane), a similar framework exists where two boron atoms are linked by two bridging hydrogens via three-center two-electron ($3c-2e^{-}$) banana bonds.

Both molecules adopt this edge-sharing tetrahedral geometry to complete the octet or stable configuration of their central atoms.
