Sr3Hg is Cementite structured and crystallizes in the orthorhombic Pnma space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 3-coordinate geometry to three equivalent Hg(1) atoms. In the second Sr site, Sr(2) is bonded in a bent 150 degrees geometry to two equivalent Hg(1) atoms. Hg(1) is bonded in a 8-coordinate geometry to two equivalent Sr(2) and six equivalent Sr(1) atoms.
Sr3Hg is Cementite structured and crystallizes in the orthorhombic Pnma space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 3-coordinate geometry to three equivalent Hg(1) atoms. There are a spread of Sr(1)-Hg(1) bond distances ranging from 3.36-3.77 Å. In the second Sr site, Sr(2) is bonded in a bent 150 degrees geometry to two equivalent Hg(1) atoms. There is one shorter (3.30 Å) and one longer (3.35 Å) Sr(2)-Hg(1) bond length. Hg(1) is bonded in a 8-coordinate geometry to two equivalent Sr(2) and six equivalent Sr(1) atoms.
