Th3O2 is Corundum structured and crystallizes in the trigonal R-3c space group. Th(1) is bonded in a distorted rectangular see-saw-like geometry to four equivalent O(1) atoms. O(1) is bonded to six equivalent Th(1) atoms to form a mixture of edge, face, and corner-sharing OTh6 octahedra. The corner-sharing octahedral tilt angles range from 49-50°.
Th3O2 is Corundum structured and crystallizes in the trigonal R-3c space group. Th(1) is bonded in a distorted rectangular see-saw-like geometry to four equivalent O(1) atoms. There are two shorter (2.54 Å) and two longer (2.64 Å) Th(1)-O(1) bond lengths. O(1) is bonded to six equivalent Th(1) atoms to form a mixture of edge, face, and corner-sharing OTh6 octahedra. The corner-sharing octahedral tilt angles range from 49-50°.
