BaZnO2 crystallizes in the trigonal P3_121 space group. Ba(1) is bonded in a 8-coordinate geometry to eight equivalent O(1) atoms. Zn(1) is bonded to four equivalent O(1) atoms to form corner-sharing ZnO4 tetrahedra. O(1) is bonded in a 2-coordinate geometry to four equivalent Ba(1) and two equivalent Zn(1) atoms.
BaZnO2 crystallizes in the trigonal P3_121 space group. Ba(1) is bonded in a 8-coordinate geometry to eight equivalent O(1) atoms. There are a spread of Ba(1)-O(1) bond distances ranging from 2.69-3.27 Å. Zn(1) is bonded to four equivalent O(1) atoms to form corner-sharing ZnO4 tetrahedra. There are two shorter (1.92 Å) and two longer (2.03 Å) Zn(1)-O(1) bond lengths. O(1) is bonded in a 2-coordinate geometry to four equivalent Ba(1) and two equivalent Zn(1) atoms.
