You might like to add it to COD :-)
Sure.
Let me a few days to add the 50 crystal structures lacking in the
Crystallography Open Database. There is some opposition in the world
to attain this target and not a lot of help from the crystallographers
themselves (one should ask why :-().

So far as I know (I may be wrong :-) ordered atomic positions for the two
requested compounds, with supposed formulae *Ba2TeO4 *and *Ba2TeO5*, have
not been determined. The closest I found were as I wrote: *"Sr Te O6 and Ba

It is true that the PDF-4+ is a commercial database: this means that
sharing the information taken from the database (as recently done here) is
an explicit violation of copyrights of ICDD and the violator might be
legally prosecuted. When

PDF4 is a commercial database of d-spacings and unit cells derived from
them. It does not normally contain atomic positions, and not all structures
in PDF4 have been determined. ICSD does contain atomic positions if they
have been determined.
Both PDF4 and ICSD are
Dear Riza:
I think you have not a crystallographic problem; it is a chemical
problem. Perhaps you must revise your chemical syntesis. It seems to
me you get some impurity phase probably with alumina.
Good luck. Yours sincerely,
