CaDyV4O12 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. Dy(1) is bonded in a 6-coordinate geometry to two equivalent O(2), two equivalent O(3), and two equivalent O(5) atoms. 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 corner-sharing VO6 octahedra. The corner-sharing octahedral tilt angles range from 16-31°. There are five inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one Ca(1) and two equivalent V(1) atoms. In the second O site, O(2) is bonded in a distorted square co-planar geometry to one Ca(1), one Dy(1), and two equivalent V(1) atoms. In the third O site, O(3) is bonded in a 3-coordinate geometry to one Dy(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 distorted T-shaped geometry to one Dy(1) and two equivalent V(1) atoms.
