Ba crystallizes in the orthorhombic Cmcm space group. There are two inequivalent Ba sites. In the first Ba site, Ba(1) is bonded in a 5-coordinate geometry to two equivalent Ba(1) and three equivalent Ba(2) atoms. In the second Ba site, Ba(2) is bonded to two equivalent Ba(2) and three equivalent Ba(1) atoms to form distorted corner-sharing BaBa5 trigonal bipyramids.
Ba crystallizes in the orthorhombic Cmcm space group. There are two inequivalent Ba sites. In the first Ba site, Ba(1) is bonded in a 5-coordinate geometry to two equivalent Ba(1) and three equivalent Ba(2) atoms. Both Ba(1)-Ba(1) bond lengths are 4.24 Å. There is one shorter (3.43 Å) and two longer (3.76 Å) Ba(1)-Ba(2) bond lengths. In the second Ba site, Ba(2) is bonded to two equivalent Ba(2) and three equivalent Ba(1) atoms to form distorted corner-sharing BaBa5 trigonal bipyramids. Both Ba(2)-Ba(2) bond lengths are 3.30 Å.
