The material described by Rb2Hg7 crystallizes in the trigonal P-3m1 space group. Rb(1) is bonded in a 12-coordinate geometry to twelve equivalent Hg(1) atoms. There are two inequivalent Hg sites. In the first Hg site, Hg(2) is bonded in a distorted cuboctahedral geometry to six equivalent Hg(1) atoms. In the second Hg site, Hg(1) is bonded in a 9-coordinate geometry to four equivalent Rb(1), one Hg(2), and four equivalent Hg(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
