BaNa crystallizes in the cubic Fd-3m space group. Na(1) is bonded in a distorted hexagonal planar geometry to two equivalent Ba(2) and four equivalent Ba(1) atoms. There are two inequivalent Ba sites. In the first Ba site, Ba(1) is bonded in a 9-coordinate geometry to six equivalent Na(1) and three equivalent Ba(2) atoms. In the second Ba site, Ba(2) is bonded to six equivalent Na(1) and six equivalent Ba(1) atoms to form face-sharing BaBa6Na6 cuboctahedra.
BaNa crystallizes in the cubic Fd-3m space group. Na(1) is bonded in a distorted hexagonal planar geometry to two equivalent Ba(2) and four equivalent Ba(1) atoms. Both Na(1)-Ba(2) bond lengths are 4.29 Å. There are two shorter (4.09 Å) and two longer (4.20 Å) Na(1)-Ba(1) bond lengths. There are two inequivalent Ba sites. In the first Ba site, Ba(1) is bonded in a 9-coordinate geometry to six equivalent Na(1) and three equivalent Ba(2) atoms. All Ba(1)-Ba(2) bond lengths are 3.96 Å. In the second Ba site, Ba(2) is bonded to six equivalent Na(1) and six equivalent Ba(1) atoms to form face-sharing BaBa6Na6 cuboctahedra.
