Eu3Ni4Ga4 crystallizes in the cubic I-43m space group. Eu(1) is bonded in a 12-coordinate geometry to four equivalent Ni(1) and eight equivalent Ga(1) atoms. Ni(1) is bonded in a 10-coordinate geometry to three equivalent Eu(1), three equivalent Ni(1), and four equivalent Ga(1) atoms. Ga(1) is bonded in a 10-coordinate geometry to six equivalent Eu(1) and four equivalent Ni(1) atoms.
Eu3Ni4Ga4 crystallizes in the cubic I-43m space group. Eu(1) is bonded in a 12-coordinate geometry to four equivalent Ni(1) and eight equivalent Ga(1) atoms. All Eu(1)-Ni(1) bond lengths are 3.08 Å. There are four shorter (3.05 Å) and four longer (3.51 Å) Eu(1)-Ga(1) bond lengths.
