NaBa2MgReO6 crystallizes in the orthorhombic Immm space group. Na(1) is bonded in a square co-planar geometry to four equivalent O(1) atoms. Ba(1) is bonded in a 9-coordinate geometry to one Mg(1), four equivalent O(1), and four equivalent O(2) atoms. Mg(1) is bonded in a square co-planar geometry to two equivalent Ba(1) and four equivalent O(1) atoms. Re(1) is bonded in an octahedral geometry to two equivalent O(2) and four equivalent O(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded to one Na(1), two equivalent Ba(1), one Mg(1), and one Re(1) atom to form a mixture of distorted edge, corner, and face-sharing OBa2NaMgRe trigonal bipyramids. In the second O site, O(2) is bonded in a distorted single-bond geometry to four equivalent Ba(1) and one Re(1) atom.
