SrNdV4O12 crystallizes in the orthorhombic Amm2 space group. Sr(1) is bonded to two equivalent O(2), two equivalent O(3), four equivalent O(1), and four equivalent O(5) atoms to form SrO12 cuboctahedra that share corners with four equivalent Sr(1)O12 cuboctahedra, corners with eight equivalent Nd(1)O12 cuboctahedra, and faces with eight equivalent V(1)O6 octahedra. Nd(1) is bonded to two equivalent O(2), two equivalent O(3), four equivalent O(1), and four equivalent O(4) atoms to form NdO12 cuboctahedra that share corners with four equivalent Nd(1)O12 cuboctahedra, corners with eight equivalent Sr(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, faces with two equivalent Sr(1)O12 cuboctahedra, and faces with two equivalent Nd(1)O12 cuboctahedra. The corner-sharing octahedral tilt angles range from 6-13°. There are five inequivalent O sites. In the first O site, O(1) is bonded in a distorted linear geometry to one Sr(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 Sr(1), one Nd(1), and two equivalent V(1) atoms. In the third O site, O(3) is bonded in a 2-coordinate geometry to one Sr(1), 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 Nd(1) and two equivalent V(1) atoms. In the fifth O site, O(5) is bonded in a distorted square co-planar geometry to two equivalent Sr(1) and two equivalent V(1) atoms.
