NaMgLaRe crystallizes in the trigonal R3m space group. Na(1) is bonded in a 10-coordinate geometry to four equivalent Mg(1), three equivalent La(1), and three equivalent Re(1) atoms. There is one shorter (2.42 Å) and three longer (3.43 Å) Na(1)-Mg(1) bond lengths. All Na(1)-La(1) bond lengths are 3.02 Å. All Na(1)-Re(1) bond lengths are 3.15 Å. Mg(1) is bonded in a 5-coordinate geometry to four equivalent Na(1), one La(1), and three equivalent Re(1) atoms. The Mg(1)-La(1) bond length is 2.42 Å. All Mg(1)-Re(1) bond lengths are 3.02 Å. La(1) is bonded in a distorted linear geometry to three equivalent Na(1), one Mg(1), and one Re(1) atom. The La(1)-Re(1) bond length is 2.42 Å. Re(1) is bonded in a 1-coordinate geometry to three equivalent Na(1), three equivalent Mg(1), and one La(1) atom.
