The compound described by Ba2Mg(IrGe)4 crystallizes in the orthorhombic Cmcm space group. Ba(1) is bonded in a 18-coordinate geometry to two equivalent Ba(1), two equivalent Mg(1), two equivalent Ir(1), four equivalent Ir(2), four equivalent Ge(1), and four equivalent Ge(2) atoms. Mg(1) is bonded in a 8-coordinate geometry to four equivalent Ba(1), two equivalent Ir(1), two equivalent Ir(2), two equivalent Ge(1), and two 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 Mg(1), 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 two equivalent Ba(1), one Mg(1), two equivalent Ge(1), and two equivalent Ge(2) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to four equivalent Ba(1), one Mg(1), two equivalent Ir(1), and two equivalent Ir(2) atoms. In the second Ge site, Ge(2) is bonded in a 7-coordinate geometry to four equivalent Ba(1), one Mg(1), two equivalent Ir(1), and two equivalent Ir(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
