(a) A column of SbO6 and strongly elongated AgO6 octahedra in AgHg3SbO6. The coordination of one Hg atom is indicated; dashed lines denote distances longer than 2.78 Å. Displacement ellipsoids are drawn at the 50% probability level. (b) A related column of SbO6 octahedra and twisted trigonal NaO6 prisms in Sr3NaSbO6 (K4CdCl6 type; Battle et al., 2001). One Sr2+ ion with eight coordinating O atoms is also shown. The tilt of the octahedra is about 45.3°. All unlabelled atoms are oxygen. [Symmetry codes: (i) -x, -y, -z; (ii) ; (iii) x-y, -y, .] |
