The material described by EuGa2Ge4 crystallizes in the orthorhombic Cmcm space group. Eu(1) is bonded in a 14-coordinate geometry to four equivalent Ga(1), four equivalent Ge(1), and six equivalent Ge(2) atoms. Ga(1) is bonded in a 6-coordinate geometry to two equivalent Eu(1), two equivalent Ga(1), one Ge(1), and one Ge(2) atom. There are two inequivalent Ge sites. In the first Ge site, Ge(2) is bonded in a 7-coordinate geometry to three equivalent Eu(1), one Ga(1), one Ge(2), and two equivalent Ge(1) atoms. In the second Ge site, Ge(1) is bonded in a 6-coordinate geometry to two equivalent Eu(1), one Ga(1), one Ge(1), and two equivalent Ge(2) atoms. is represented by the CIF card [CIF]
