Materials Data on Fe2P12W by Materials Project
WFe2P12 crystallizes in the orthorhombic Pbcn space group. The structure is three-dimensional. W6+ is bonded in a 8-coordinate geometry to eight P1- atoms. There are a spread of W–P bond distances ranging from 2.48–2.57 Å. Fe3+ is bonded to six P1- atoms to form FeP6 octahedra that share corners with two equivalent FeP6 octahedra and corners with five PP3W tetrahedra. The corner-sharing octahedral tilt angles are 55°. There are a spread of Fe–P bond distances ranging from 2.16–2.26 Å. There are six inequivalent P1- sites. In the first P1- site, P1- is bonded in a 4-coordinate geometry to one W6+, one Fe3+, and two P1- atoms. There are one shorter (2.25 Å) and one longer (2.28 Å) P–P bond lengths. In the second P1- site, P1- is bonded to one W6+ and three P1- atoms to form distorted PP3W tetrahedra that share corners with four equivalent FeP6 octahedra and corners with three equivalent PP3W tetrahedra. The corner-sharing octahedra tilt angles range from 56–76°. There are two shorter (2.25 Å) and one longer (2.27 Å) P–P bond lengths. In the third P1- site, P1- is bonded in a 4-coordinate geometry to one W6+, one Fe3+, and two P1- atoms. There are one shorter (2.26 Å) and one longer (2.28 Å) P–P bond lengths. In the fourth P1- site, P1- is bonded in a distorted single-bond geometry to one Fe3+ and three P1- atoms. In the fifth P1- site, P1- is bonded to two equivalent Fe3+ and two P1- atoms to form distorted PFe2P2 tetrahedra that share a cornercorner with one FeP6 octahedra and corners with two equivalent PFe2P2 tetrahedra. The corner-sharing octahedral tilt angles are 69°. In the sixth P1- site, P1- is bonded in a 4-coordinate geometry to one W6+, one Fe3+, and two P1- atoms.
