The compound described by Sr2Pb3P3O13 crystallizes in the hexagonal P6_3/m space group. Sr(1) is bonded in a 9-coordinate geometry to three equivalent O(1), three equivalent O(2), and three equivalent O(4) atoms. Pb(1) is bonded to one O(2), one O(3), and four equivalent O(4) atoms to form distorted PbO6 pentagonal pyramids that share corners with six equivalent Pb(1)O6 pentagonal pyramids, corners with three equivalent P(1)O4 tetrahedra, and  an edgeedge with one P(1)O4 tetrahedra. P(1) is bonded to one O(1), one O(2), and two equivalent O(4) atoms to form PO4 tetrahedra that share corners with three equivalent Pb(1)O6 pentagonal pyramids and  an edgeedge with one Pb(1)O6 pentagonal pyramid. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to two equivalent Sr(1) and one P(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to two equivalent Sr(1), one Pb(1), and one P(1) atom. In the third O site, O(3) is bonded in a trigonal planar geometry to three equivalent Pb(1) atoms. In the fourth O site, O(4) is bonded in a distorted single-bond geometry to one Sr(1), two equivalent Pb(1), and one P(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
