What is structure of (HPO3) metaphosphoric acid?

 Meta Phosphoric acid exit as cyclic structure, the sodium salts of trimer and hexamer is very famous salts.

Cyclic trimer contains three P-O-P Oxy linkage or bond

 

Hexamer of meta phosphoric acid exist as sodium salt which is called  sodium metaphophate or sodium polymetaphosphate and it is commercially  known as "CALGON" and use as water softener.
