The structure described by 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. is represented by the Crystallographic Information File (CIF) [CIF]
