The crystal structure described by La6Ni6P17 crystallizes in the cubic I-43m space group. La(1) is bonded in a 13-coordinate geometry to four equivalent Ni(1), one P(1), two equivalent P(2), and six equivalent P(3) atoms. Ni(1) is bonded in a distorted square co-planar geometry to four equivalent La(1) and four equivalent P(3) atoms. There are three inequivalent P sites. In the first P site, P(1) is bonded in an octahedral geometry to six equivalent La(1) atoms. In the second P site, P(2) is bonded in a 6-coordinate geometry to three equivalent La(1) and three equivalent P(3) atoms. In the third P site, P(3) is bonded in a 6-coordinate geometry to three equivalent La(1), two equivalent Ni(1), and one P(2) atom. is represented by the CIF card [CIF]
