TLDR
In this article, the structure of the first heteropolyanion with an X:M ratio of 1:2 was determined from single crystal X-ray studies of the sodium salt; the idealized anion has 2m symmetry and consists of a shell of WO6 octahedra and PO4 tetrahedra made up of four PW2O13 groups linked by corner sharing and a sodium atom is situated in the centre of the polyanion.Abstract:

The Structure of a Meso-Type Heteropolyion of Tetrahydrogen Disodium Dodecamolybdohexaphosphonate(III) (6−) Contained in [NEt4]6[H4Na2(PH)6Mo12O54]·4H2O
TL;DR: The structure of [NEt4]6[H4Na2(PH)6Mo12O54]·4H2O (1) has been determined by the single-crystal X-ray method as mentioned in this paper.

Synthesis of Colorless (6/5)-Molybdophosphonate, Na2H5[(C2H5)4N]3(HP)5Mo6O33
TL;DR: In this article, the existence of a new type of heteropoly complex with a composition of Mo/P = 6/5 was elucidated and the formation conditions and the IR spectroscopic characteristics were compared with those of well-established pentamolybdodiphosphonate.
