Dy(BiO2)3 is Ilmenite-like structured and crystallizes in the trigonal R-3 space group. There are two inequivalent Dy sites. In the first Dy site, Dy(1) is bonded in an octahedral geometry to six equivalent O(1) atoms. In the second Dy site, Dy(2) is bonded in an octahedral geometry to six equivalent O(2) atoms. Bi(1) is bonded in a 6-coordinate geometry to three equivalent O(1) and three equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded to one Dy(1) and three equivalent Bi(1) atoms to form a mixture of distorted corner and edge-sharing ODyBi3 trigonal pyramids. In the second O site, O(2) is bonded to one Dy(2) and three equivalent Bi(1) atoms to form a mixture of distorted corner and edge-sharing ODyBi3 trigonal pyramids.
