The material described by La3ReO8 crystallizes in the monoclinic P2_1/m space group. There are three inequivalent La sites. In the first La site, La(1) is bonded in a 7-coordinate geometry to one O(3), one O(4), one O(6), two equivalent O(1), and two equivalent O(2) atoms. In the second La site, La(2) is bonded in a 8-coordinate geometry to one O(3), one O(5), two equivalent O(2), and four equivalent O(1) atoms. In the third La site, La(3) is bonded in a 7-coordinate geometry to one O(4), one O(5), one O(6), two equivalent O(1), and two equivalent O(2) atoms. Re(1) is bonded in an octahedral geometry to one O(3), one O(4), one O(5), one O(6), and two equivalent O(2) atoms. There are six inequivalent O sites. In the first O site, O(1) is bonded to one La(1), one La(3), and two equivalent La(2) atoms to form a mixture of edge and corner-sharing OLa4 tetrahedra. In the second O site, O(2) is bonded in a 4-coordinate geometry to one La(1), one La(2), one La(3), and one Re(1) atom. In the third O site, O(3) is bonded in a 3-coordinate geometry to one La(1), one La(2), and one Re(1) atom. In the fourth O site, O(4) is bonded in a 3-coordinate geometry to one La(1), one La(3), and one Re(1) atom. In the fifth O site, O(5) is bonded in a 3-coordinate geometry to one La(2), one La(3), and one Re(1) atom. In the sixth O site, O(6) is bonded in a distorted single-bond geometry to one La(1), one La(3), and one Re(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
