The crystal structure described by Ni2SiP is Magnesium tetraboride-derived structured and crystallizes in the orthorhombic Pbca space group. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 6-coordinate geometry to four equivalent Si(1) and two equivalent P(1) atoms. In the second Ni site, Ni(2) is bonded in a 3-coordinate geometry to two equivalent Si(1) and four equivalent P(1) atoms. Si(1) is bonded in a 8-coordinate geometry to two equivalent Ni(2), four equivalent Ni(1), one Si(1), and one P(1) atom. P(1) is bonded in a 7-coordinate geometry to two equivalent Ni(1), four equivalent Ni(2), and one Si(1) atom. is represented by the CIF file [CIF]
