The compound described by NaEu(ReO5)4 crystallizes in the tetragonal P-4n2 space group. Na(1) is bonded in a 8-coordinate geometry to four equivalent O(1) and four equivalent O(2) atoms. Eu(1) is bonded in a 8-coordinate geometry to four equivalent O(3) and four equivalent O(5) atoms. Re(1) is bonded in a tetrahedral geometry to one O(1), one O(2), one O(3), and one O(4) atom. There are five inequivalent O sites. In the first O site, O(4) is bonded in a single-bond geometry to one Re(1) atom. In the second O site, O(1) is bonded in a distorted single-bond geometry to one Na(1) and one Re(1) atom. In the third O site, O(5) is bonded in a single-bond geometry to one Eu(1) atom. In the fourth O site, O(2) is bonded in a distorted bent 150 degrees geometry to one Na(1) and one Re(1) atom. In the fifth O site, O(3) is bonded in a bent 150 degrees geometry to one Eu(1) and one Re(1) atom. is represented by the CIF file [CIF]
