Is peroxoborate and perborate the same thing? Recently I came across the following question:-


  Preparation of Sodium Peroxoborate- Equations


The term peroxoborate came from the fact that it has the peroxo bond $\ce{-O-O}-$. So, it should be strictly called peroxoborate. But some books says  peroxoborate while other books say perborate. Is it true?

I googled sodium perborate.  Wikipedia recognizes the compound as sodium perborate. Then, I googled sodium peroxoborate, the following message appear:-



So, is peroxoborate and perborate the same thing? If so, why some book says  peroxoborate while othe books perborate? It should be strictly called peroxoborate since it contains the peroxo bond $\ce{-O-O}-$.



Update

This is what written in Weller, M.; Overton, T.; Rourke, J.; Armstrong, F. Inorganic Chemistry, 6th ed:-


  Sodium perborate is used as a bleach  in laundry powder, automatic dishwasher powders, and whitening toothpastes. Although the formula is given as $\ce{NaBO3.H2O}$ or $\ce{NaBO3.4H2O}$, the compound contains th peroxide anion, $\ce{O2^{2-}}$ and is more accurately given by $\ce{Na2[B2(O2)2(OH)4].6H2O}$.


But this is what written in Lee, J.D. Inorganic chemistry


  $$\ce{2NaBO2 + 2H2O2 + 6H2O -&gt; Na2[B2(O2)2(OH)4].6H2O }$$
  Sodium peroxoborate is used as a brightener in washing powder. It is compatible with enzymes which are added to some biological powders. 


So, what is the correct name:- sodium perborate or sodium peroxoborate?
This is necessarily  not  a chemistry answer but is a continuation of aventurin's answer.



Google ngram viewer is an online search engine h  that charts frequencies of any word or short sentence found in the sources printed between 1800 and 2012 in American English, British English etc.



So, here is the Google ngram for peroxoborate and perborate. 


So, you can see that perborate is more often used than peroxoborate. Though, the correct name (IUPAC name) is tetrahydroxidodi-µ-peroxido-diborate, people often mention the compound sodium perborate. Sodium peroxoborate seems to be obsolete.
