Na Mg Be Ga
NaMgBeGa crystallizes in the trigonal R3m space group. Na(1) is bonded in a distorted q6 geometry to three equivalent Mg(1), three equivalent Be(1), and four equivalent Ga(1) atoms. All Na(1)-Mg(1) bond lengths are 2.70 Å. All Na(1)-Be(1) bond lengths are 2.70 Å. There are three shorter (2.74 Å) and one longer (3.23 Å) Na(1)-Ga(1) bond length. Mg(1) is bonded in a 9-coordinate geometry to three equivalent Na(1), three equivalent Be(1), and three equivalent Ga(1) atoms. All Mg(1)-Be(1) bond lengths are 2.74 Å. All Mg(1)-Ga(1) bond lengths are 2.70 Å. Be(1) is bonded in a single-bond geometry to three equivalent Na(1), three equivalent Mg(1), and one Ga(1) atom. The Be(1)-Ga(1) bond length is 0.84 Å. Ga(1) is bonded in a single-bond geometry to four equivalent Na(1), three equivalent Mg(1), and one Be(1) atom.
