Ce4Re6O19 crystallizes in the cubic I23 space group. Ce(1) is bonded in a 10-coordinate geometry to one O(2), three equivalent O(1), and six equivalent O(3) atoms. Re(1) is bonded to two equivalent O(1) and four equivalent O(3) atoms to form a mixture of corner and edge-sharing ReO6 octahedra. The corner-sharing octahedral tilt angles are 56°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to two equivalent Ce(1) and two equivalent Re(1) atoms. In the second O site, O(2) is bonded in a tetrahedral geometry to four equivalent Ce(1) atoms. In the third O site, O(3) is bonded in a 3-coordinate geometry to two equivalent Ce(1) and two equivalent Re(1) atoms.
Ce4Re6O19 crystallizes in the cubic I23 space group. Ce(1) is bonded in a 10-coordinate geometry to one O(2), three equivalent O(1), and six equivalent O(3) atoms. The Ce(1)-O(2) bond length is 2.44 Å. All Ce(1)-O(1) bond lengths are 2.47 Å. There are three shorter (2.54 Å) and three longer (2.99 Å) Ce(1)-O(3) bond lengths. Re(1) is bonded to two equivalent O(1) and four equivalent O(3) atoms to form a mixture of corner and edge-sharing ReO6 octahedra. The corner-sharing octahedral tilt angles are 56°. Both Re(1)-O(1) bond lengths are 2.05 Å. There are two shorter (1.99 Å) and two longer (2.00 Å) Re(1)-O(3) bond lengths. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 4-coordinate geometry to two equivalent Ce(1) and two equivalent Re(1) atoms. In the second O site, O(2) is bonded in a tetrahedral geometry to four equivalent Ce(1) atoms. In the third O site, O(3) is bonded in a 3-coordinate geometry to two equivalent Ce(1) and two equivalent Re(1) atoms.
