Ba2In is Cotunnite structured and crystallizes in the orthorhombic Pnma space group. There are two inequivalent Ba sites. In the first Ba site, Ba(1) is bonded in a 3-coordinate geometry to three equivalent In(1) atoms. In the second Ba site, Ba(2) is bonded to four equivalent In(1) atoms to form a mixture of distorted corner and edge-sharing BaIn4 tetrahedra. In(1) is bonded in a 7-coordinate geometry to three equivalent Ba(1) and four equivalent Ba(2) atoms.
Ba2In is Cotunnite structured and crystallizes in the orthorhombic Pnma space group. There are two inequivalent Ba sites. In the first Ba site, Ba(1) is bonded in a 3-coordinate geometry to three equivalent In(1) atoms. There is one shorter (3.70 Å) and two longer (3.75 Å) Ba(1)-In(1) bond lengths. In the second Ba site, Ba(2) is bonded to four equivalent In(1) atoms to form a mixture of distorted corner and edge-sharing BaIn4 tetrahedra. There is one shorter (3.57 Å) and three longer (3.66 Å) Ba(2)-In(1) bond lengths. In(1) is bonded in a 7-coordinate geometry to three equivalent Ba(1) and four equivalent Ba(2) atoms.
