RhPd2Si crystallizes in the triclinic P1 space group. Rh(1) is bonded in a distorted single-bond geometry to one Pd(1), one Pd(2), and one Si(1) atom. The Rh(1)-Pd(1) bond length is 1.93 Å. The Rh(1)-Pd(2) bond length is 0.66 Å. The Rh(1)-Si(1) bond length is 2.62 Å. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 1-coordinate geometry to one Rh(1) and two equivalent Si(1) atoms. There is one shorter (2.55 Å) and one longer (2.70 Å) Pd(1)-Si(1) bond length. In the second Pd site, Pd(2) is bonded in a single-bond geometry to one Rh(1) and two equivalent Si(1) atoms. There is one shorter (2.26 Å) and one longer (2.65 Å) Pd(2)-Si(1) bond length. Si(1) is bonded in a 5-coordinate geometry to one Rh(1), two equivalent Pd(1), and two equivalent Pd(2) atoms.
