Materials Data on Ce4Si4N7ClO3 by Materials Project
Abstract
Ce4Si4N7O3Cl crystallizes in the orthorhombic P2_12_12_1 space group. The structure is three-dimensional. there are four inequivalent Ce3+ sites. In the first Ce3+ site, Ce3+ is bonded to three N3-, three O2-, and one Cl1- atom to form distorted CeN3ClO3 hexagonal pyramids that share corners with two equivalent CeN4ClO2 pentagonal bipyramids, corners with three SiN3O tetrahedra, an edgeedge with one CeN4ClO2 pentagonal bipyramid, and edges with three SiN3O tetrahedra. There are one shorter (2.59 Å) and two longer (2.60 Å) Ce–N bond lengths. There are a spread of Ce–O bond distances ranging from 2.32–2.57 Å. The Ce–Cl bond length is 2.98 Å. In the second Ce3+ site, Ce3+ is bonded in a 7-coordinate geometry to four N3-, two O2-, and one Cl1- atom. There are a spread of Ce–N bond distances ranging from 2.48–2.63 Å. There are one shorter (2.59 Å) and one longer (2.62 Å) Ce–O bond lengths. The Ce–Cl bond length is 3.25 Å. In the third Ce3+ site, Ce3+ is bonded to four N3-, two O2-, and one Cl1- atom to form distorted CeN4ClO2 pentagonal bipyramids that share corners with two equivalent CeN3ClO3 hexagonal pyramids, corners with three SiN3O tetrahedra, an edgeedge with one CeN3ClO3 hexagonal pyramid, andmore »
