The structure described by BaLaSi2 crystallizes in the orthorhombic Cmcm space group. Ba(1) is bonded in a 6-coordinate geometry to six equivalent Si(1) atoms. La(1) is bonded in a 8-coordinate geometry to eight equivalent Si(1) atoms. Si(1) is bonded in a 9-coordinate geometry to three equivalent Ba(1), four equivalent La(1), and two equivalent Si(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
