The compound described by BaZnGeO4 crystallizes in the hexagonal P6_3 space group. There are three inequivalent Ba sites. In the first Ba site, Ba(1) is bonded in a distorted q6 geometry to three equivalent O(2), three equivalent O(3), and three equivalent O(4) atoms. In the second Ba site, Ba(2) is bonded in a distorted q6 geometry to three equivalent O(2) and six equivalent O(1) atoms. In the third Ba site, Ba(3) is bonded in a distorted q6 geometry to three equivalent O(2), three equivalent O(3), and three equivalent O(4) atoms. Zn(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form ZnO4 tetrahedra that share corners with four equivalent Ge(1)O4 tetrahedra. Ge(1) is bonded to one O(1), one O(2), one O(3), and one O(4) atom to form GeO4 tetrahedra that share corners with four equivalent Zn(1)O4 tetrahedra. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 120 degrees geometry to two equivalent Ba(2), one Zn(1), and one Ge(1) atom. In the second O site, O(2) is bonded in a distorted linear geometry to one Ba(1), one Ba(2), one Ba(3), one Zn(1), and one Ge(1) atom. In the third O site, O(3) is bonded in a distorted bent 120 degrees geometry to one Ba(1), one Ba(3), one Zn(1), and one Ge(1) atom. In the fourth O site, O(4) is bonded in a distorted bent 120 degrees geometry to one Ba(1), one Ba(3), one Zn(1), and one Ge(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
