BaSrSi4 is beta-prime palladium aluminum-derived structured and crystallizes in the orthorhombic C222_1 space group. Ba(1) is bonded in a 8-coordinate geometry to four equivalent Si(1) and four equivalent Si(2) atoms. Sr(1) is bonded in a 8-coordinate geometry to four equivalent Si(1) and four equivalent Si(2) atoms. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded in a 7-coordinate geometry to two equivalent Ba(1), two equivalent Sr(1), one Si(1), and two equivalent Si(2) atoms. In the second Si site, Si(2) is bonded in a 7-coordinate geometry to two equivalent Ba(1), two equivalent Sr(1), one Si(2), and two equivalent Si(1) atoms.
BaSrSi4 is beta-prime palladium aluminum-derived structured and crystallizes in the orthorhombic C222_1 space group. Ba(1) is bonded in a 8-coordinate geometry to four equivalent Si(1) and four equivalent Si(2) atoms. There are two shorter (3.33 Å) and two longer (3.43 Å) Ba(1)-Si(1) bond lengths. There are two shorter (3.38 Å) and two longer (3.40 Å) Ba(1)-Si(2) bond lengths. Sr(1) is bonded in a 8-coordinate geometry to four equivalent Si(1) and four equivalent Si(2) atoms. There are two shorter (3.28 Å) and two longer (3.32 Å) Sr(1)-Si(1) bond lengths. There are two shorter (3.36 Å) and two longer (3.37 Å) Sr(1)-Si(2) bond lengths. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded in a 7-coordinate geometry to two equivalent Ba(1), two equivalent Sr(1), one Si(1), and two equivalent Si(2) atoms. The Si(1)-Si(1) bond length is 2.41 Å. Both Si(1)-Si(2) bond lengths are 2.43 Å. In the second Si site, Si(2) is bonded in a 7-coordinate geometry to two equivalent Ba(1), two equivalent Sr(1), one Si(2), and two equivalent Si(1) atoms.
