The structure described by BaSiC is delta Molybdenum Boride-derived structured and crystallizes in the orthorhombic Pnma space group. There are two inequivalent Ba sites. In the first Ba site, Ba(1) is bonded in a 9-coordinate geometry to two equivalent Si(2), three equivalent Si(1), and four equivalent C(1) atoms. In the second Ba site, Ba(2) is bonded in a 9-coordinate geometry to two equivalent Si(1), three equivalent Si(2), and four equivalent C(1) atoms. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded in a 2-coordinate geometry to two equivalent Ba(2), three equivalent Ba(1), and two equivalent C(1) atoms. In the second Si site, Si(2) is bonded in a 2-coordinate geometry to two equivalent Ba(1), three equivalent Ba(2), and two equivalent C(1) atoms. C(1) is bonded in a 7-coordinate geometry to two equivalent Ba(1), two equivalent Ba(2), one Si(1), one Si(2), and one C(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
