Ba2Ge3 crystallizes in the orthorhombic Imm2 space group. Ba(1) is bonded in a 9-coordinate geometry to three equivalent Ge(1), three equivalent Ge(2), and three equivalent Ge(3) atoms. There are three inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to six equivalent Ba(1), one Ge(2), and two equivalent Ge(3) atoms. In the second Ge site, Ge(2) is bonded in a 7-coordinate geometry to six equivalent Ba(1) and one Ge(1) atom. In the third Ge site, Ge(3) is bonded in a 8-coordinate geometry to six equivalent Ba(1) and two equivalent Ge(1) atoms.
Ba2Ge3 crystallizes in the orthorhombic Imm2 space group. Ba(1) is bonded in a 9-coordinate geometry to three equivalent Ge(1), three equivalent Ge(2), and three equivalent Ge(3) atoms. There are two shorter (3.47 Å) and one longer (3.75 Å) Ba(1)-Ge(1) bond length. There is one shorter (3.51 Å) and two longer (3.57 Å) Ba(1)-Ge(2) bond lengths. There are two shorter (3.48 Å) and one longer (3.52 Å) Ba(1)-Ge(3) bond length. There are three inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to six equivalent Ba(1), one Ge(2), and two equivalent Ge(3) atoms. The Ge(1)-Ge(2) bond length is 2.46 Å. Both Ge(1)-Ge(3) bond lengths are 2.54 Å. In the second Ge site, Ge(2) is bonded in a 7-coordinate geometry to six equivalent Ba(1) and one Ge(1) atom. In the third Ge site, Ge(3) is bonded in a 8-coordinate geometry to six equivalent Ba(1) and two equivalent Ge(1) atoms.
