Materials Data on Ca2BN2Cl by Materials Project
Abstract
Ca2BN2Cl crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are two inequivalent Ca2+ sites. In the first Ca2+ site, Ca2+ is bonded to four N3- and two equivalent Cl1- atoms to form CaN4Cl2 octahedra that share corners with five equivalent CaN3Cl3 octahedra and edges with seven CaN4Cl2 octahedra. The corner-sharing octahedra tilt angles range from 6–70°. There are a spread of Ca–N bond distances ranging from 2.41–2.56 Å. Both Ca–Cl bond lengths are 2.94 Å. In the second Ca2+ site, Ca2+ is bonded to three N3- and three equivalent Cl1- atoms to form a mixture of distorted edge and corner-sharing CaN3Cl3 octahedra. The corner-sharing octahedra tilt angles range from 6–70°. There are two shorter (2.35 Å) and one longer (2.57 Å) Ca–N bond lengths. There are one shorter (2.87 Å) and two longer (2.98 Å) Ca–Cl bond lengths. B3+ is bonded in a linear geometry to two N3- atoms. There is one shorter (1.34 Å) and one longer (1.35 Å) B–N bond length. There are two inequivalent N3- sites. In the first N3- site, N3- is bonded to three Ca2+ and one B3+ atom to form distorted NCa3B tetrahedra that share corners with two equivalent NCa3Bmore »
