SrHgIn3 crystallizes in the tetragonal I4mm space group. Sr(1) is bonded in a 16-coordinate geometry to four equivalent Hg(1), four equivalent In(2), and eight equivalent In(1) atoms. Hg(1) is bonded in a 9-coordinate geometry to four equivalent Sr(1), one In(2), and four equivalent In(1) atoms. There are two inequivalent In sites. In the first In site, In(1) is bonded in a 2-coordinate geometry to four equivalent Sr(1), two equivalent Hg(1), and two equivalent In(2) atoms. In the second In site, In(2) is bonded in a 9-coordinate geometry to four equivalent Sr(1), one Hg(1), and four equivalent In(1) atoms.
SrHgIn3 crystallizes in the tetragonal I4mm space group. Sr(1) is bonded in a 16-coordinate geometry to four equivalent Hg(1), four equivalent In(2), and eight equivalent In(1) atoms. All Sr(1)-Hg(1) bond lengths are 3.58 Å. All Sr(1)-In(2) bond lengths are 3.65 Å. There are four shorter (3.85 Å) and four longer (4.03 Å) Sr(1)-In(1) bond lengths. Hg(1) is bonded in a 9-coordinate geometry to four equivalent Sr(1), one In(2), and four equivalent In(1) atoms. The Hg(1)-In(2) bond length is 2.76 Å. All Hg(1)-In(1) bond lengths are 2.94 Å. There are two inequivalent In sites. In the first In site, In(1) is bonded in a 2-coordinate geometry to four equivalent Sr(1), two equivalent Hg(1), and two equivalent In(2) atoms. Both In(1)-In(2) bond lengths are 2.96 Å. In the second In site, In(2) is bonded in a 9-coordinate geometry to four equivalent Sr(1), one Hg(1), and four equivalent In(1) atoms.
