Beryllium chloride ($BeC{l}_2$) forms a chlorobridged dimer in the vapor phase due to its small size and high polarizing power. This allows it to form covalent bonds and achieve a stable electron configuration by bridging chlorine atoms between two beryllium atoms.

The structure of the dimer is:

$$Cl-Be(Cl)-Be-Cl$$
