Sr3BPO3 crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 6-coordinate geometry to three equivalent P(1) and three equivalent O(1) atoms. In the second Sr site, Sr(2) is bonded to two equivalent P(1) and six equivalent O(1) atoms to form corner-sharing SrP2O6 hexagonal bipyramids. B(1) is bonded in a trigonal planar geometry to three equivalent O(1) atoms. P(1) is bonded in a body-centered cubic geometry to two equivalent Sr(2) and six equivalent Sr(1) atoms. O(1) is bonded to two equivalent Sr(1), two equivalent Sr(2), and one B(1) atom to form a mixture of distorted edge, corner, and face-sharing OSr4B trigonal bipyramids.
