The material described by Ba2Ir4Ge5 crystallizes in the orthorhombic Cmcm space group. Ba(1) is bonded in a 20-coordinate geometry to two equivalent Ba(1), four equivalent Ir(1), four equivalent Ir(2), two equivalent Ge(3), four equivalent Ge(1), and four equivalent Ge(2) atoms. There are two inequivalent Ir sites. In the first Ir site, Ir(2) is bonded in a 5-coordinate geometry to four equivalent Ba(1), one Ge(3), two equivalent Ge(1), and two equivalent Ge(2) atoms. In the second Ir site, Ir(1) is bonded in a 5-coordinate geometry to four equivalent Ba(1), one Ge(3), two equivalent Ge(1), and two equivalent Ge(2) atoms. There are three inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 8-coordinate geometry to four equivalent Ba(1), two equivalent Ir(1), and two equivalent Ir(2) atoms. In the second Ge site, Ge(2) is bonded in a 6-coordinate geometry to four equivalent Ba(1), two equivalent Ir(1), and two equivalent Ir(2) atoms. In the third Ge site, Ge(3) is bonded in a 4-coordinate geometry to four equivalent Ba(1), two equivalent Ir(1), and two equivalent Ir(2) atoms. is represented by the CIF file [CIF]
