Na Na Ga Pb
Na2GaPb crystallizes in the triclinic P1 space group. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded in a 3-coordinate geometry to one Na(2) and two equivalent Pb(1) atoms. The Na(1)-Na(2) bond length is 1.65 Å. There is one shorter (3.42 Å) and one longer (3.75 Å) Na(1)-Pb(1) bond length. In the second Na site, Na(2) is bonded in a 4-coordinate geometry to one Na(1) and three equivalent Ga(1) atoms. There are a spread of Na(2)-Ga(1) bond distances ranging from 2.79-3.35 Å. Ga(1) is bonded in a distorted single-bond geometry to three equivalent Na(2) and one Pb(1) atom. The Ga(1)-Pb(1) bond length is 1.08 Å. Pb(1) is bonded in a single-bond geometry to two equivalent Na(1) and one Ga(1) atom.
