NaMn2Pb crystallizes in the triclinic P1 space group. Na(1) is bonded in a single-bond geometry to four equivalent Mn(1) and one Pb(1) atom. There are a spread of Na(1)-Mn(1) bond distances ranging from 2.52-3.41 Å. The Na(1)-Pb(1) bond length is 1.21 Å. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded in a 11-coordinate geometry to four equivalent Na(1), two equivalent Mn(1), three equivalent Mn(2), and two equivalent Pb(1) atoms. Both Mn(1)-Mn(1) bond lengths are 3.11 Å. There are a spread of Mn(1)-Mn(2) bond distances ranging from 2.98-3.17 Å. There is one shorter (2.74 Å) and one longer (3.03 Å) Mn(1)-Pb(1) bond length. In the second Mn site, Mn(2) is bonded in a distorted bent 120 degrees geometry to three equivalent Mn(1) and two equivalent Pb(1) atoms. There is one shorter (2.74 Å) and one longer (3.03 Å) Mn(2)-Pb(1) bond length. Pb(1) is bonded in a single-bond geometry to one Na(1), two equivalent Mn(1), and two equivalent Mn(2) atoms.
