Materials Data on Ba(Ni5P3)2 by Materials Project
Ba(Ni5P3)2 crystallizes in the orthorhombic Cmce space group. The structure is three-dimensional. Ba2+ is bonded in a 12-coordinate geometry to twelve P3- atoms. There are a spread of Ba–P bond distances ranging from 3.25–3.70 Å. There are four inequivalent Ni+1.60+ sites. In the first Ni+1.60+ site, Ni+1.60+ is bonded to four P3- atoms to form a mixture of distorted corner and edge-sharing NiP4 trigonal pyramids. There are a spread of Ni–P bond distances ranging from 2.31–2.47 Å. In the second Ni+1.60+ site, Ni+1.60+ is bonded to four P3- atoms to form a mixture of distorted corner and edge-sharing NiP4 tetrahedra. There are two shorter (2.26 Å) and two longer (2.35 Å) Ni–P bond lengths. In the third Ni+1.60+ site, Ni+1.60+ is bonded to four P3- atoms to form a mixture of corner and edge-sharing NiP4 tetrahedra. There are a spread of Ni–P bond distances ranging from 2.19–2.27 Å. In the fourth Ni+1.60+ site, Ni+1.60+ is bonded to four P3- atoms to form a mixture of corner and edge-sharing NiP4 tetrahedra. There are a spread of Ni–P bond distances ranging from 2.21–2.33 Å. There are three inequivalent P3- sites. In the first P3- site, P3- is bonded in a 6-coordinate geometry to two equivalent Ba2+ and six Ni+1.60+ atoms. In the second P3- site, P3- is bonded in a 6-coordinate geometry to three equivalent Ba2+ and six Ni+1.60+ atoms. In the third P3- site, P3- is bonded in a 9-coordinate geometry to one Ba2+ and eight Ni+1.60+ atoms.
