U2PdSi3 crystallizes in the orthorhombic Pmm2 space group. The structure is three-dimensional. there are two inequivalent U5+ sites. In the first U5+ site, U5+ is bonded in a distorted q4 geometry to ten Si4- atoms. There are a spread of U–Si bond distances ranging from 2.96–3.06 Å. In the second U5+ site, U5+ is bonded in a 8-coordinate geometry to eight Si4- atoms. There are a spread of U–Si bond distances ranging from 2.98–3.17 Å. Pd2+ is bonded in a trigonal planar geometry to three Si4- atoms. All Pd–Si bond lengths are 2.42 Å. There are three inequivalent Si4- sites. In the first Si4- site, Si4- is bonded in a 9-coordinate geometry to six U5+ and three Si4- atoms. There are one shorter (2.33 Å) and two longer (2.36 Å) Si–Si bond lengths. In the second Si4- site, Si4- is bonded in a 2-coordinate geometry to six U5+, two equivalent Pd2+, and one Si4- atom. In the third Si4- site, Si4- is bonded in a 1-coordinate geometry to six U5+, one Pd2+, and two equivalent Si4- atoms.
