Na Be W W
NaBeW2 crystallizes in the triclinic P1 space group. Na(1) is bonded in a 8-coordinate geometry to two equivalent Na(1), two equivalent Be(1), two equivalent W(1), and two equivalent W(2) atoms. Both Na(1)-Na(1) bond lengths are 2.62 Å. There is one shorter (2.38 Å) and one longer (2.74 Å) Na(1)-Be(1) bond length. There is one shorter (2.39 Å) and one longer (3.39 Å) Na(1)-W(1) bond length. There is one shorter (2.39 Å) and one longer (3.39 Å) Na(1)-W(2) bond length. Be(1) is bonded in a 3-coordinate geometry to two equivalent Na(1), one W(1), and one W(2) atom. The Be(1)-W(1) bond length is 1.97 Å. The Be(1)-W(2) bond length is 2.19 Å. There are two inequivalent W sites. In the first W site, W(1) is bonded in a 2-coordinate geometry to two equivalent Na(1) and one Be(1) atom. In the second W site, W(2) is bonded in a 2-coordinate geometry to two equivalent Na(1) and one Be(1) atom.
