The structure described by BaCaGe crystallizes in the orthorhombic Pnma space group. Ba(1) is bonded in a 5-coordinate geometry to five equivalent Ge(1) atoms. Ca(1) is bonded to four equivalent Ge(1) atoms to form a mixture of distorted corner and edge-sharing CaGe4 tetrahedra. Ge(1) is bonded in a 9-coordinate geometry to five equivalent Ba(1) and four equivalent Ca(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
