SrHg3 crystallizes in the orthorhombic Pnma space group. Sr(1) is bonded to four equivalent Hg(2) and eight equivalent Hg(1) atoms to form a mixture of 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.
SrHg3 crystallizes in the orthorhombic Pnma space group. Sr(1) is bonded to four equivalent Hg(2) and eight equivalent Hg(1) atoms to form a mixture of face and corner-sharing SrHg12 cuboctahedra. There are a spread of Sr(1)-Hg(2) bond distances ranging from 3.39-3.47 Å. There are a spread of Sr(1)-Hg(1) bond distances ranging from 3.41-3.56 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.
