PrSbO4 crystallizes in the monoclinic P2_1/c space group. Pr(1) is bonded in a 8-coordinate geometry to one O(2), one O(4), three equivalent O(1), and three equivalent O(3) atoms. Sb(1) is bonded to one O(1), one O(3), two equivalent O(2), and two equivalent O(4) atoms to form corner-sharing SbO6 octahedra. The corner-sharing octahedral tilt angles range from 33-43°. There are four inequivalent O sites. In the first O site, O(1) is bonded to three equivalent Pr(1) and one Sb(1) atom to form a mixture of distorted edge and corner-sharing OPr3Sb tetrahedra. In the second O site, O(2) is bonded in a distorted trigonal non-coplanar geometry to one Pr(1) and two equivalent Sb(1) atoms. In the third O site, O(3) is bonded in a 4-coordinate geometry to three equivalent Pr(1) and one Sb(1) atom. In the fourth O site, O(4) is bonded in a 3-coordinate geometry to one Pr(1) and two equivalent Sb(1) atoms.
