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 infinity1[(TeO2/1O4/2)({TeO2/1O2/2}2O4/2)] 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.
