The compound described by U2PdNiGe2 crystallizes in the orthorhombic Pmc2_1 space group. There are two inequivalent U sites. In the first U site, U(1) is bonded in a 12-coordinate geometry to four equivalent Pd(1), two equivalent Ni(1), two equivalent Ge(1), and four equivalent Ge(2) atoms. In the second U site, U(2) is bonded in a 12-coordinate geometry to two equivalent Pd(1), four equivalent Ni(1), two equivalent Ge(2), and four equivalent Ge(1) atoms. Pd(1) is bonded in a 10-coordinate geometry to two equivalent U(2), four equivalent U(1), two equivalent Ge(1), and two equivalent Ge(2) atoms. Ni(1) is bonded in a 10-coordinate geometry to two equivalent U(1), four equivalent U(2), two equivalent Ge(1), and two equivalent Ge(2) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 10-coordinate geometry to two equivalent U(1), four equivalent U(2), two equivalent Pd(1), and two equivalent Ni(1) atoms. In the second Ge site, Ge(2) is bonded in a 10-coordinate geometry to two equivalent U(2), four equivalent U(1), two equivalent Pd(1), and two equivalent Ni(1) atoms. is represented by the CIF card [CIF]
