Materials Data on La4Br3ClO4 by Materials Project
La4O4Br3Cl is Matlockite-derived structured and crystallizes in the orthorhombic Amm2 space group. The structure is three-dimensional. there are three inequivalent La3+ sites. In the first La3+ site, La3+ is bonded in a 4-coordinate geometry to four O2- and five Br1- atoms. There are two shorter (2.39 Å) and two longer (2.40 Å) La–O bond lengths. There are four shorter (3.33 Å) and one longer (3.54 Å) La–Br bond lengths. In the second La3+ site, La3+ is bonded in a 4-coordinate geometry to four O2- and four equivalent Br1- atoms. All La–O bond lengths are 2.40 Å. All La–Br bond lengths are 3.31 Å. In the third La3+ site, La3+ is bonded in a 4-coordinate geometry to four O2-, three Br1-, and two equivalent Cl1- atoms. There are a spread of La–O bond distances ranging from 2.39–2.42 Å. There are two shorter (3.31 Å) and one longer (3.50 Å) La–Br bond lengths. Both La–Cl bond lengths are 3.26 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded to four La3+ atoms to form a mixture of edge and corner-sharing OLa4 tetrahedra. In the second O2- site, O2- is bonded to four La3+ atoms to form a mixture of edge and corner-sharing OLa4 tetrahedra. In the third O2- site, O2- is bonded to four La3+ atoms to form a mixture of edge and corner-sharing OLa4 tetrahedra. There are two inequivalent Br1- sites. In the first Br1- site, Br1- is bonded in a 5-coordinate geometry to five La3+ atoms. In the second Br1- site, Br1- is bonded in a 5-coordinate geometry to five La3+ atoms. Cl1- is bonded in a 4-coordinate geometry to four equivalent La3+ atoms.
