Y(BiO2)3 is Ilmenite-like structured and crystallizes in the trigonal R-3 space group. There are two inequivalent Y sites. In the first Y site, Y(1) is bonded in an octahedral geometry to six equivalent O(1) atoms. In the second Y site, Y(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 Y(1) and three equivalent Bi(1) atoms to form a mixture of distorted corner and edge-sharing OYBi3 trigonal pyramids. In the second O site, O(2) is bonded to one Y(2) and three equivalent Bi(1) atoms to form a mixture of distorted corner and edge-sharing OYBi3 trigonal pyramids.
