Al Al V Pb
VAl2Pb crystallizes in the monoclinic Cm space group. V(1) is bonded in a 4-coordinate geometry to four equivalent Al(1), four equivalent Al(2), and one Pb(1) atom. There are a spread of V(1)-Al(1) bond distances ranging from 3.37-3.45 Å. There are a spread of V(1)-Al(2) bond distances ranging from 2.15-2.28 Å. The V(1)-Pb(1) bond length is 3.41 Å. There are two inequivalent Al sites. In the first Al site, Al(1) is bonded in a 12-coordinate geometry to four equivalent V(1), four equivalent Al(1), and four equivalent Pb(1) atoms. All Al(1)-Al(1) bond lengths are 2.97 Å. There are a spread of Al(1)-Pb(1) bond distances ranging from 3.36-3.45 Å. In the second Al site, Al(2) is bonded in a 4-coordinate geometry to four equivalent V(1) and four equivalent Pb(1) atoms. There are a spread of Al(2)-Pb(1) bond distances ranging from 3.36-3.45 Å. Pb(1) is bonded in a 13-coordinate geometry to one V(1), four equivalent Al(1), four equivalent Al(2), and four equivalent Pb(1) atoms. All Pb(1)-Pb(1) bond lengths are 2.97 Å.
