Ba Ga Pb Pb
BaGaPb2 crystallizes in the monoclinic Cm space group. Ba(1) is bonded to four equivalent Ga(1) and eight equivalent Pb(1) atoms to form a mixture of distorted corner and face-sharing BaGa4Pb8 cuboctahedra. There are a spread of Ba(1)-Ga(1) bond distances ranging from 3.26-3.72 Å. There are a spread of Ba(1)-Pb(1) bond distances ranging from 3.08-4.11 Å. Ga(1) is bonded in a 8-coordinate geometry to four equivalent Ba(1) and four equivalent Pb(1) atoms. There are two shorter (3.08 Å) and two longer (3.34 Å) Ga(1)-Pb(1) bond lengths. Pb(1) is bonded in a 3-coordinate geometry to four equivalent Ba(1) and two equivalent Ga(1) atoms.
