BaSrBi3 is Magnesium tetraboride-derived structured and crystallizes in the orthorhombic Pnna space group. Ba(1) is bonded in a 8-coordinate geometry to two equivalent Bi(1) and eight equivalent Bi(2) atoms. Sr(1) is bonded in a 8-coordinate geometry to four equivalent Bi(1) and four equivalent Bi(2) atoms. There are two inequivalent Bi sites. In the first Bi site, Bi(1) is bonded in a 8-coordinate geometry to two equivalent Ba(1), four equivalent Sr(1), and two equivalent Bi(2) atoms. In the second Bi site, Bi(2) is bonded in a 8-coordinate geometry to four equivalent Ba(1), two equivalent Sr(1), one Bi(1), and one Bi(2) atom.
BaSrBi3 is Magnesium tetraboride-derived structured and crystallizes in the orthorhombic Pnna space group. Ba(1) is bonded in a 8-coordinate geometry to two equivalent Bi(1) and eight equivalent Bi(2) atoms. Both Ba(1)-Bi(1) bond lengths are 3.68 Å. There are a spread of Ba(1)-Bi(2) bond distances ranging from 3.58-4.24 Å. Sr(1) is bonded in a 8-coordinate geometry to four equivalent Bi(1) and four equivalent Bi(2) atoms. There are two shorter (3.57 Å) and two longer (3.65 Å) Sr(1)-Bi(1) bond lengths. There are two shorter (3.43 Å) and two longer (3.52 Å) Sr(1)-Bi(2) bond lengths. There are two inequivalent Bi sites. In the first Bi site, Bi(1) is bonded in a 8-coordinate geometry to two equivalent Ba(1), four equivalent Sr(1), and two equivalent Bi(2) atoms. Both Bi(1)-Bi(2) bond lengths are 3.33 Å. In the second Bi site, Bi(2) is bonded in a 8-coordinate geometry to four equivalent Ba(1), two equivalent Sr(1), one Bi(1), and one Bi(2) atom. The Bi(2)-Bi(2) bond length is 3.16 Å.
