EuPdGa3 crystallizes in the orthorhombic Cmcm space group. Eu(1) is bonded in a 17-coordinate geometry to five equivalent Pd(1), four equivalent Ga(1), and eight equivalent Ga(2) atoms. Pd(1) is bonded in a 5-coordinate geometry to five equivalent Eu(1), one 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 distorted single-bond geometry to four equivalent Eu(1), one Pd(1), and four equivalent Ga(2) atoms. In the second Ga site, Ga(2) is bonded in a distorted L-shaped geometry to four equivalent Eu(1), two equivalent Pd(1), and two equivalent Ga(1) atoms.
EuPdGa3 crystallizes in the orthorhombic Cmcm space group. Eu(1) is bonded in a 17-coordinate geometry to five equivalent Pd(1), four equivalent Ga(1), and eight equivalent Ga(2) atoms. There are a spread of Eu(1)-Pd(1) bond distances ranging from 3.28-3.64 Å. There are two shorter (3.15 Å) and two longer (3.28 Å) Eu(1)-Ga(1) bond lengths. There are four shorter (3.36 Å) and four longer (3.42 Å) Eu(1)-Ga(2) bond lengths. Pd(1) is bonded in a 5-coordinate geometry to five equivalent Eu(1), one Ga(1), and four equivalent Ga(2) atoms. The Pd(1)-Ga(1) bond length is 2.48 Å. All Pd(1)-Ga(2) bond lengths are 2.54 Å. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a distorted single-bond geometry to four equivalent Eu(1), one Pd(1), and four equivalent Ga(2) atoms. All Ga(1)-Ga(2) bond lengths are 2.63 Å. In the second Ga site, Ga(2) is bonded in a distorted L-shaped geometry to four equivalent Eu(1), two equivalent Pd(1), and two equivalent Ga(1) atoms.
