The polymeric structure of BeCl2 is due to its electron deficient nature. ... It has only four electrons in valence shell and can accept two pairs of electrons from neighbouring chlorine atoms to complete their octet And This is mainly because beryllium is a small atom with high relative ionization energy (900 kJ/mol) and therefore does not form cations. It rather attracts a bonding pair of electrons towards itself only. ... This gives them a covalent character.
