The material described by BaSi crystallizes in the orthorhombic Cmcm space group. Ba(1) is bonded in a 7-coordinate geometry to seven equivalent Si(1) atoms. Si(1) is bonded to seven equivalent Ba(1) atoms to form a mixture of distorted corner, edge, and face-sharing SiBa7 hexagonal pyramids. is represented by the Crystallographic Information File (CIF) [CIF]
