The structure described by SrDyCr4O12 crystallizes in the orthorhombic Amm2 space group. Sr(1) is bonded in a 10-coordinate geometry to two equivalent O(2), four equivalent O(1), and four equivalent O(5) atoms. Dy(1) is bonded in a 6-coordinate geometry to two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms. Cr(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 CrO6 octahedra. The corner-sharing octahedral tilt angles range from 13-26°. There are five inequivalent O sites. In the first O site, O(1) is bonded in a 2-coordinate geometry to one Sr(1) and two equivalent Cr(1) atoms. In the second O site, O(2) is bonded in a distorted rectangular see-saw-like geometry to one Sr(1), one Dy(1), and two equivalent Cr(1) atoms. In the third O site, O(3) is bonded in a 3-coordinate geometry to one Dy(1) and two equivalent Cr(1) atoms. In the fourth O site, O(4) is bonded in a distorted T-shaped geometry to one Dy(1) and two equivalent Cr(1) atoms. In the fifth O site, O(5) is bonded in a 2-coordinate geometry to two equivalent Sr(1) and two equivalent Cr(1) atoms. is represented by the CIF card [CIF]
