Materials Data on Ta5(NiP)4 by Materials Project

Abstract

Ta5(NiP)4 crystallizes in the tetragonal I4/m space group. The structure is three-dimensional. there are two inequivalent Ta sites. In the first Ta site, Ta is bonded in a 5-coordinate geometry to five equivalent P atoms. There are a spread of Ta–P bond distances ranging from 2.57–2.71 Å. In the second Ta site, Ta is bonded in a square co-planar geometry to four equivalent P atoms. All Ta–P bond lengths are 2.62 Å. Ni is bonded in a 3-coordinate geometry to three equivalent P atoms. There are two shorter (2.21 Å) and one longer (2.25 Å) Ni–P bond lengths. P is bonded in a 9-coordinate geometry to six Ta and three equivalent Ni atoms.
