Materials Data on Ce5C2Cl9 by Materials Project

Abstract

Ce5C2Cl9 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are five inequivalent Ce3+ sites. In the first Ce3+ site, Ce3+ is bonded in a 6-coordinate geometry to one C3- and five Cl1- atoms. The Ce–C bond length is 2.37 Å. There are a spread of Ce–Cl bond distances ranging from 2.86–3.29 Å. In the second Ce3+ site, Ce3+ is bonded to two C3- and five Cl1- atoms to form distorted corner-sharing CeC2Cl5 pentagonal bipyramids. There are one shorter (2.43 Å) and one longer (2.50 Å) Ce–C bond lengths. There are a spread of Ce–Cl bond distances ranging from 2.94–3.13 Å. In the third Ce3+ site, Ce3+ is bonded in a 8-coordinate geometry to two C3- and six Cl1- atoms. There are one shorter (2.45 Å) and one longer (2.49 Å) Ce–C bond lengths. There are a spread of Ce–Cl bond distances ranging from 2.93–3.49 Å. In the fourth Ce3+ site, Ce3+ is bonded in a 8-coordinate geometry to two C3- and six Cl1- atoms. There are one shorter (2.45 Å) and one longer (2.51 Å) Ce–C bond lengths. There are a spread of Ce–Cl bond distances ranging from 2.90–3.37 Å. In the fifth Ce3+ site, Ce3+ is bonded in a 7-coordinate geometry to one C3- and six Cl1- atoms. The Ce–C bond length is 2.39 Å. There are a spread of Ce–Cl bond distances ranging from 2.77–3.28 Å. There are two inequivalent C3- sites. In the first C3- site, C3- is bonded in a 5-coordinate geometry to four Ce3+ and one C3- atom. The C–C bond length is 1.48 Å. In the second C3- site, C3- is bonded in a 5-coordinate geometry to four Ce3+ and one C3- atom. There are ten inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a 4-coordinate geometry to four Ce3+ atoms. In the second Cl1- site, Cl1- is bonded in a distorted L-shaped geometry to two Ce3+ atoms. In the third Cl1- site, Cl1- is bonded in an L-shaped geometry to two Ce3+ atoms. In the fourth Cl1- site, Cl1- is bonded in a distorted trigonal non-coplanar geometry to three Ce3+ atoms. In the fifth Cl1- site, Cl1- is bonded in a distorted see-saw-like geometry to four Ce3+ atoms. In the sixth Cl1- site, Cl1- is bonded in a distorted trigonal planar geometry to three Ce3+ atoms. In the seventh Cl1- site, Cl1- is bonded in a distorted trigonal pyramidal geometry to four Ce3+ atoms. In the eighth Cl1- site, Cl1- is bonded in a 4-coordinate geometry to four Ce3+ atoms. In the ninth Cl1- site, Cl1- is bonded in a distorted square co-planar geometry to four Ce3+ atoms. In the tenth Cl1- site, Cl1- is bonded in an L-shaped geometry to two Ce3+ atoms.
