PdNiSi2 crystallizes in the orthorhombic Pmc2_1 space group. Pd(1) is bonded in a 8-coordinate geometry to two equivalent Ni(1), two equivalent Si(2), and four equivalent Si(1) atoms. Ni(1) is bonded in a 8-coordinate geometry to two equivalent Pd(1), two equivalent Si(1), and four equivalent Si(2) atoms. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded in a 6-coordinate geometry to four equivalent Pd(1), two equivalent Ni(1), and two equivalent Si(2) atoms. In the second Si site, Si(2) is bonded in a 8-coordinate geometry to two equivalent Pd(1), four equivalent Ni(1), and two equivalent Si(1) atoms.
PdNiSi2 crystallizes in the orthorhombic Pmc2_1 space group. Pd(1) is bonded in a 8-coordinate geometry to two equivalent Ni(1), two equivalent Si(2), and four equivalent Si(1) atoms. Both Pd(1)-Ni(1) bond lengths are 2.79 Å. There is one shorter (2.40 Å) and one longer (2.62 Å) Pd(1)-Si(2) bond length. There are two shorter (2.47 Å) and two longer (2.54 Å) Pd(1)-Si(1) bond lengths. Ni(1) is bonded in a 8-coordinate geometry to two equivalent Pd(1), two equivalent Si(1), and four equivalent Si(2) atoms. There is one shorter (2.30 Å) and one longer (2.31 Å) Ni(1)-Si(1) bond length. There are two shorter (2.30 Å) and two longer (2.45 Å) Ni(1)-Si(2) bond lengths. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded in a 6-coordinate geometry to four equivalent Pd(1), two equivalent Ni(1), and two equivalent Si(2) atoms. Both Si(1)-Si(2) bond lengths are 2.71 Å. In the second Si site, Si(2) is bonded in a 8-coordinate geometry to two equivalent Pd(1), four equivalent Ni(1), and two equivalent Si(1) atoms.
