Ag2Hg2(TeO4)3

Red single crystals of disilver(I) dimercury(II) tris­[tetra­oxo­tellurate(VI)], Ag₂Hg₂(TeO₄)₃, were obtained under hydro­thermal conditions at 523 K. The structure is built up of _∞¹[(TeO_2/1O_4/2)({TeO_2/1O_2/2}₂O_4/2)] chains, with an overall composition [TeO₄]²⁻, that run parallel to the crystallographic a axis. Distorted AgO₆ and HgO₆ polyhedra (the latter with two short and nearly collinear Hg—O bonds) link the tellurate chains into a three‐dimensional network. Except for one Te atom situated on an inversion center, all atoms occupy general positions.
