Ba(GeAs)2 crystallizes in the tetragonal P4_2mc space group. There are two inequivalent Ba sites. In the first Ba site, Ba(1) is bonded in a distorted body-centered cubic geometry to eight equivalent As(1) atoms. In the second Ba site, Ba(2) is bonded in a body-centered cubic geometry to eight equivalent As(1) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 4-coordinate geometry to one Ge(1), one Ge(2), and two equivalent As(1) atoms. In the second Ge site, Ge(2) is bonded in a 4-coordinate geometry to one Ge(1), one Ge(2), and two equivalent As(1) atoms. As(1) is bonded in a 6-coordinate geometry to two equivalent Ba(1), two equivalent Ba(2), one Ge(1), and one Ge(2) atom.
Ba(GeAs)2 crystallizes in the tetragonal P4_2mc space group. There are two inequivalent Ba sites. In the first Ba site, Ba(1) is bonded in a distorted body-centered cubic geometry to eight equivalent As(1) atoms. There are four shorter (3.51 Å) and four longer (3.58 Å) Ba(1)-As(1) bond lengths. In the second Ba site, Ba(2) is bonded in a body-centered cubic geometry to eight equivalent As(1) atoms. There are four shorter (3.41 Å) and four longer (3.48 Å) Ba(2)-As(1) bond lengths. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 4-coordinate geometry to one Ge(1), one Ge(2), and two equivalent As(1) atoms. The Ge(1)-Ge(1) bond length is 2.57 Å. The Ge(1)-Ge(2) bond length is 2.49 Å. Both Ge(1)-As(1) bond lengths are 2.43 Å. In the second Ge site, Ge(2) is bonded in a 4-coordinate geometry to one Ge(1), one Ge(2), and two equivalent As(1) atoms. The Ge(2)-Ge(2) bond length is 2.60 Å. Both Ge(2)-As(1) bond lengths are 2.43 Å. As(1) is bonded in a 6-coordinate geometry to two equivalent Ba(1), two equivalent Ba(2), one Ge(1), and one Ge(2) atom.
