CaNdV4O12 crystallizes in the orthorhombic Amm2 space group. Ca(1) is bonded in a 10-coordinate geometry to two equivalent O(2), four equivalent O(1), and four equivalent O(4) atoms. Nd(1) is bonded to two equivalent O(2), two equivalent O(3), four equivalent O(1), and four equivalent O(5) atoms to form distorted NdO12 cuboctahedra that share corners with four equivalent Nd(1)O12 cuboctahedra and faces with eight equivalent V(1)O6 octahedra. V(1) is bonded to one O(2), one O(3), one O(4), one O(5), and two equivalent O(1) atoms to form VO6 octahedra that share corners with six equivalent V(1)O6 octahedra and faces with two equivalent Nd(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles range from 12-20°. There are five inequivalent O sites. In the first O site, O(1) is bonded in a 2-coordinate geometry to one Ca(1), one Nd(1), and two equivalent V(1) atoms. In the second O site, O(2) is bonded in a distorted rectangular see-saw-like geometry to one Ca(1), one Nd(1), and two equivalent V(1) atoms. In the third O site, O(3) is bonded in a 3-coordinate geometry to one Nd(1) and two equivalent V(1) atoms. In the fourth O site, O(4) is bonded in a 2-coordinate geometry to two equivalent Ca(1) and two equivalent V(1) atoms. In the fifth O site, O(5) is bonded in a 3-coordinate geometry to two equivalent Nd(1) and two equivalent V(1) atoms.
CaNdV4O12 crystallizes in the orthorhombic Amm2 space group. Ca(1) is bonded in a 10-coordinate geometry to two equivalent O(2), four equivalent O(1), and four equivalent O(4) atoms. Both Ca(1)-O(2) bond lengths are 2.63 Å. All Ca(1)-O(1) bond lengths are 2.52 Å. There are two shorter (2.54 Å) and two longer (2.79 Å) Ca(1)-O(4) bond lengths.
