Sr3(VO4)2 crystallizes in the trigonal R-3m space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 10-coordinate geometry to one O(2) and nine equivalent O(1) atoms. In the second Sr site, Sr(2) is bonded in a 6-coordinate geometry to six equivalent O(1) atoms. V(1) is bonded in a tetrahedral geometry to one O(2) and three equivalent O(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to one Sr(2), three equivalent Sr(1), and one V(1) atom. In the second O site, O(2) is bonded in a distorted linear geometry to one Sr(1) and one V(1) atom.

In the first Sr site, Sr(1) is bonded in a 10-coordinate geometry to one O(2) and nine equivalent O(1) atoms. The Sr(1)-O(2) bond length is 2.42 Å. There are three shorter (2.59 Å) and six longer (2.87 Å) Sr(1)-O(1) bond lengths. In the second Sr site, Sr(2) is bonded in a 6-coordinate geometry to six equivalent O(1) atoms. All Sr(2)-O(1) bond lengths are 2.61 Å. V(1) is bonded in a tetrahedral geometry to one O(2) and three equivalent O(1) atoms. The V(1)-O(2) bond length is 1.70 Å. All V(1)-O(1) bond lengths are 1.72 Å. There are two inequivalent O sites.
