BiPO4 crystallizes in the trigonal P3_121 space group. Bi(1) is bonded in a 8-coordinate geometry to four equivalent O(1) and four equivalent O(2) atoms. P(1) is bonded in a tetrahedral geometry to two equivalent O(1) and two equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(2) is bonded in a distorted single-bond geometry to two equivalent Bi(1) and one P(1) atom. In the second O site, O(1) is bonded in a 2-coordinate geometry to two equivalent Bi(1) and one P(1) atom.
BiPO4 crystallizes in the trigonal P3_121 space group. Bi(1) is bonded in a 8-coordinate geometry to four equivalent O(1) and four equivalent O(2) atoms. There are two shorter (2.24 Å) and two longer (2.80 Å) Bi(1)-O(1) bond lengths. There are two shorter (2.39 Å) and two longer (2.55 Å) Bi(1)-O(2) bond lengths. P(1) is bonded in a tetrahedral geometry to two equivalent O(1) and two equivalent O(2) atoms. Both P(1)-O(1) bond lengths are 1.54 Å. Both P(1)-O(2) bond lengths are 1.54 Å. There are two inequivalent O sites. In the first O site, O(2) is bonded in a distorted single-bond geometry to two equivalent Bi(1) and one P(1) atom. In the second O site, O(1) is bonded in a 2-coordinate geometry to two equivalent Bi(1) and one P(1) atom.
