What is structure of Beryllium chloride ?

Beryllium chloride a colorless crystal. it is deliquescent and soluble in water and ethanol. And its melting, boiling point are 405 °C ,520 °C respectively. Beryllium is a discrete molecule (BeCl2-dicoordinate) in gaseous state but in solid state it    forms a 1-dimensional chain (tetra-coordinated) beryllium via chlorine bridges bond. It is a as Lewis acid monomeric (BeCl2) form and is used as a catalyst for (FCR) Friedel-Crafts reactions.
