The material described by EuNi2Ga3 crystallizes in the orthorhombic Cmcm space group. Eu(1) is bonded in a 21-coordinate geometry to two equivalent Eu(1), eight equivalent Ni(1), three equivalent Ga(1), and eight equivalent Ga(2) atoms. Ni(1) is bonded in a 6-coordinate geometry to four equivalent Eu(1), two equivalent Ga(1), and four equivalent Ga(2) atoms. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 11-coordinate geometry to three equivalent Eu(1), four equivalent Ni(1), two equivalent Ga(1), and two equivalent Ga(2) atoms. In the second Ga site, Ga(2) is bonded in a 11-coordinate geometry to four equivalent Eu(1), four equivalent Ni(1), one Ga(1), and two equivalent Ga(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
