The structure described by 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. is represented by the CIF card [CIF]
