The structure described by Fe2SiP crystallizes in the orthorhombic Pmc2_1 space group. There are two inequivalent Fe sites. In the first Fe site, Fe(1) is bonded in a 6-coordinate geometry to four equivalent Si(1) and two equivalent P(1) atoms. In the second Fe site, Fe(2) is bonded in a 6-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 Fe(2), four equivalent Fe(1), and two equivalent P(1) atoms. P(1) is bonded in a 8-coordinate geometry to two equivalent Fe(1), four equivalent Fe(2), and two equivalent Si(1) atoms. is represented by the CIF file [CIF]
