Na Na Rh Pb
Na2RhPb is Magnesium tetraboride-derived structured and crystallizes in the triclinic P1 space group. There are two inequivalent Na sites. In the first Na site, Na(1) is bonded in a 6-coordinate geometry to two equivalent Na(2), two equivalent Rh(1), and two equivalent Pb(1) atoms. There is one shorter (1.55 Å) and one longer (2.07 Å) Na(1)-Na(2) bond length. There is one shorter (2.53 Å) and one longer (2.88 Å) Na(1)-Rh(1) bond length. There is one shorter (3.26 Å) and one longer (3.54 Å) Na(1)-Pb(1) bond length. In the second Na site, Na(2) is bonded in a 8-coordinate geometry to two equivalent Na(1), four equivalent Rh(1), and two equivalent Pb(1) atoms. There are a spread of Na(2)-Rh(1) bond distances ranging from 2.76-3.30 Å. There is one shorter (3.31 Å) and one longer (3.58 Å) Na(2)-Pb(1) bond length. Rh(1) is bonded in a 9-coordinate geometry to two equivalent Na(1), four equivalent Na(2), and three equivalent Pb(1) atoms. There are a spread of Rh(1)-Pb(1) bond distances ranging from 2.38-3.20 Å. Pb(1) is bonded in a 9-coordinate geometry to two equivalent Na(1), two equivalent Na(2), three equivalent Rh(1), and two equivalent Pb(1) atoms. Both Pb(1)-Pb(1) bond lengths are 3.29 Å.
