Re2PbO8 crystallizes in the trigonal P31m space group. There are two inequivalent Re sites. In the first Re site, Re(1) is bonded to one O(1), one O(4), and two equivalent O(5) atoms to form ReO4 tetrahedra that share corners with two equivalent Pb(2)O6 pentagonal pyramids. In the second Re site, Re(2) is bonded to one O(2), one O(6), and two equivalent O(3) atoms to form ReO4 tetrahedra that share corners with two equivalent Pb(2)O6 pentagonal pyramids. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a 6-coordinate geometry to three equivalent O(2) and three equivalent O(4) atoms. In the second Pb site, Pb(2) is bonded to three equivalent O(3) and three equivalent O(5) atoms to form distorted PbO6 pentagonal pyramids that share corners with three equivalent Re(1)O4 tetrahedra and corners with three equivalent Re(2)O4 tetrahedra. There are six inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to one Re(1) atom. In the second O site, O(2) is bonded in a distorted bent 150 degrees geometry to one Re(2) and one Pb(1) atom. In the third O site, O(3) is bonded in a distorted bent 150 degrees geometry to one Re(2) and one Pb(2) atom. In the fourth O site, O(4) is bonded in a distorted single-bond geometry to one Re(1) and one Pb(1) atom. In the fifth O site, O(5) is bonded in a distorted bent 150 degrees geometry to one Re(1) and one Pb(2) atom. In the sixth O site, O(6) is bonded in a single-bond geometry to one Re(2) atom.
