The crystal structure described by LaPdSi crystallizes in the monoclinic P2_1/c space group. There are two inequivalent La sites. In the first La site, La(1) is bonded in a 13-coordinate geometry to one La(1), two equivalent Pd(2), five equivalent Pd(1), one Si(1), and four equivalent Si(2) atoms. In the second La site, La(2) is bonded to one Pd(1), four equivalent Pd(2), two equivalent Si(2), and five equivalent Si(1) atoms to form a mixture of distorted edge and face-sharing LaSi7Pd5 cuboctahedra. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 5-coordinate geometry to one La(2), five equivalent La(1), and three equivalent Si(2) atoms. In the second Pd site, Pd(2) is bonded in a 9-coordinate geometry to two equivalent La(1), four equivalent La(2), one Si(2), and two equivalent Si(1) atoms. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded in a 9-coordinate geometry to one La(1), five equivalent La(2), two equivalent Pd(2), and one Si(1) atom. In the second Si site, Si(2) is bonded in a 4-coordinate geometry to two equivalent La(2), four equivalent La(1), one Pd(2), and three equivalent Pd(1) atoms. is represented by the CIF file [CIF]
