Materials Data on U2NiGe2Pd by Materials Project
U2PdNiGe2 crystallizes in the orthorhombic Pmc2_1 space group. The structure is three-dimensional. there are two inequivalent U sites. In the first U site, U is bonded in a 12-coordinate geometry to four equivalent Pd, two equivalent Ni, and six Ge atoms. There are two shorter (3.00 Å) and two longer (3.17 Å) U–Pd bond lengths. There are one shorter (2.93 Å) and one longer (3.07 Å) U–Ni bond lengths. There are a spread of U–Ge bond distances ranging from 3.05–3.24 Å. In the second U site, U is bonded in a 12-coordinate geometry to two equivalent Pd, four equivalent Ni, and six Ge atoms. There are one shorter (2.99 Å) and one longer (3.10 Å) U–Pd bond lengths. There are two shorter (2.96 Å) and two longer (3.27 Å) U–Ni bond lengths. There are a spread of U–Ge bond distances ranging from 2.97–3.05 Å. Pd is bonded in a 10-coordinate geometry to six U and four Ge atoms. There are a spread of Pd–Ge bond distances ranging from 2.60–2.77 Å. Ni is bonded in a 10-coordinate geometry to six U and four Ge atoms. There are a spread of Ni–Ge bond distances ranging from 2.50–2.66 Å. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 10-coordinate geometry to six U, two equivalent Pd, and two equivalent Ni atoms. In the second Ge site, Ge is bonded in a 10-coordinate geometry to six U, two equivalent Pd, and two equivalent Ni atoms.
