Tm2Pd2Si is delta Molybdenum Boride-derived structured and crystallizes in the orthorhombic Pnnm space group. There are two inequivalent Tm sites. In the first Tm site, Tm(1) is bonded in a 9-coordinate geometry to three equivalent Pd(1), four equivalent Pd(2), and two equivalent Si(1) atoms. In the second Tm site, Tm(2) is bonded in a 9-coordinate geometry to two equivalent Pd(2), three equivalent Pd(1), and four equivalent Si(1) atoms. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 7-coordinate geometry to three equivalent Tm(1), three equivalent Tm(2), and one Si(1) atom. In the second Pd site, Pd(2) is bonded in a 9-coordinate geometry to two equivalent Tm(2), four equivalent Tm(1), one Pd(2), and two equivalent Si(1) atoms. Si(1) is bonded in a 10-coordinate geometry to two equivalent Tm(1), four equivalent Tm(2), one Pd(1), two equivalent Pd(2), and one Si(1) atom.

In the first Tm site, Tm(1) is bonded in a 9-coordinate geometry to three equivalent Pd(1), four equivalent Pd(2), and two equivalent Si(1) atoms. There is one shorter (3.05 Å) and two longer (3.10 Å) Tm(1)-Pd(1) bond lengths. There are two shorter (3.01 Å) and two longer (3.03 Å) Tm(1)-Pd(2) bond lengths. There is one shorter (3.10 Å) and one longer (3.21 Å) Tm(1)-Si(1) bond length. In the second Tm site, Tm(2) is bonded in a 9-coordinate geometry to two equivalent Pd(2), three equivalent Pd(1), and four equivalent Si(1) atoms. There is one shorter (2.87 Å) and one longer (3.18 Å) Tm(2)-Pd(2) bond length. All Tm(2)-Pd(1) bond lengths are 2.91 Å. There are two shorter (2.92 Å) and two longer (3.07 Å) Tm(2)-Si(1) bond lengths. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 7-coordinate geometry to three equivalent Tm(1), three equivalent Tm(2), and one Si(1) atom. The Pd(1)-Si(1) bond length is 2.61 Å.
