SrHg3 is beta Cu3Ti structured and crystallizes in the orthorhombic Pmmn space group. Sr(1) is bonded to four equivalent Hg(2) and eight equivalent Hg(1) atoms to form a mixture of edge, face, and corner-sharing SrHg12 cuboctahedra. There are two inequivalent Hg sites. In the first Hg site, Hg(1) is bonded in a 4-coordinate geometry to four equivalent Sr(1) atoms. In the second Hg site, Hg(2) is bonded in a 4-coordinate geometry to four equivalent Sr(1) atoms.

Sr(1) is bonded to four equivalent Hg(2) and eight equivalent Hg(1) atoms to form a mixture of edge, face, and corner-sharing SrHg12 cuboctahedra. There are two shorter (3.34 Å) and two longer (3.45 Å) Sr(1)-Hg(2) bond lengths. There are a spread of Sr(1)-Hg(1) bond distances ranging from 3.37-3.53 Å. There are two inequivalent Hg sites. In the first Hg site, Hg(1) is bonded in a 4-coordinate geometry to four equivalent Sr(1) atoms. In the second Hg site, Hg(2) is bonded in a 4-coordinate geometry to four equivalent Sr(1) atoms.
