Materials Data on Ce(Ni5P2)2 by Materials Project
Ce(Ni5P2)2 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Ce is bonded in a 7-coordinate geometry to ten Ni and seven P atoms. There are a spread of Ce–Ni bond distances ranging from 3.17–3.29 Å. There are a spread of Ce–P bond distances ranging from 2.97–3.15 Å. There are ten inequivalent Ni sites. In the first Ni site, Ni is bonded in a distorted bent 120 degrees geometry to two equivalent Ce and two P atoms. There are one shorter (2.23 Å) and one longer (2.26 Å) Ni–P bond lengths. In the second Ni site, Ni is bonded in a distorted water-like geometry to one Ce and two equivalent P atoms. Both Ni–P bond lengths are 2.22 Å. In the third Ni site, Ni is bonded in a distorted trigonal non-coplanar geometry to three P atoms. There are one shorter (2.16 Å) and two longer (2.28 Å) Ni–P bond lengths. In the fourth Ni site, Ni is bonded in a 2-coordinate geometry to four P atoms. There are a spread of Ni–P bond distances ranging from 2.25–2.62 Å. In the fifth Ni site, Ni is bonded in a 3-coordinate geometry to three P atoms. There are one shorter (2.17 Å) and two longer (2.32 Å) Ni–P bond lengths. In the sixth Ni site, Ni is bonded in a distorted trigonal planar geometry to two equivalent Ce and three P atoms. There are one shorter (2.21 Å) and two longer (2.22 Å) Ni–P bond lengths. In the seventh Ni site, Ni is bonded in a distorted trigonal planar geometry to two equivalent Ce and three P atoms. There are one shorter (2.23 Å) and two longer (2.29 Å) Ni–P bond lengths. In the eighth Ni site, Ni is bonded in a 4-coordinate geometry to two equivalent Ce and four P atoms. There are a spread of Ni–P bond distances ranging from 2.20–2.44 Å. In the ninth Ni site, Ni is bonded in a 3-coordinate geometry to three P atoms. There are one shorter (2.20 Å) and two longer (2.31 Å) Ni–P bond lengths.
