(H9O4)2TeBr6 crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four hydrogen tetrahydrate molecules and two TeBr6 clusters. In each TeBr6 cluster, Te4+ is bonded in an octahedral geometry to six Br1- atoms. There are a spread of Te–Br bond distances ranging from 2.73–2.75 Å. There are three inequivalent Br1- sites. In the first Br1- site, Br1- is bonded in a single-bond geometry to one Te4+ atom. In the second Br1- site, Br1- is bonded in a single-bond geometry to one Te4+ atom. In the third Br1- site, Br1- is bonded in a single-bond geometry to one Te4+ atom.
