The compound described by BaNdZr4O12 crystallizes in the orthorhombic Amm2 space group. Ba(1) is bonded in a distorted q6 geometry to two equivalent O(2), four equivalent O(1), and four equivalent O(4) atoms. Nd(1) is bonded in a 6-coordinate geometry to two equivalent O(2), two equivalent O(3), and two equivalent O(5) atoms. Zr(1) is bonded to one O(2), one O(3), one O(4), one O(5), and two equivalent O(1) atoms to form corner-sharing ZrO6 octahedra. The corner-sharing octahedral tilt angles range from 6-35°. There are five inequivalent O sites. In the first O site, O(1) is bonded in a 2-coordinate geometry to one Ba(1) and two equivalent Zr(1) atoms. In the second O site, O(2) is bonded in a distorted rectangular see-saw-like geometry to one Ba(1), one Nd(1), and two equivalent Zr(1) atoms. In the third O site, O(3) is bonded in a distorted trigonal non-coplanar geometry to one Nd(1) and two equivalent Zr(1) atoms. In the fourth O site, O(4) is bonded in a distorted linear geometry to two equivalent Ba(1) and two equivalent Zr(1) atoms. In the fifth O site, O(5) is bonded in a distorted trigonal non-coplanar geometry to one Nd(1) and two equivalent Zr(1) atoms. is represented by the CIF card [CIF]
