Beryllium chloride is an electron-deficient compound because it has the two empty orbitals at the bonding level.In the solid, the BeCl2 molecules polymerise to make long chains. They do this by forming coordinate bonds (dative covalent bonds) between lone pairs on chlorine atoms and adjacent beryllium atoms.

The arrow goes from the atom which is supplying the pair of electrons to the atom with the empty orbital.
