Materials Data on Ca3BCBr2N by Materials Project
Abstract
Ca3BCNBr2 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are three inequivalent Ca2+ sites. In the first Ca2+ site, Ca2+ is bonded to two equivalent C4- and four Br1- atoms to form distorted CaC2Br4 octahedra that share corners with seven CaC2Br3N octahedra, edges with seven CaC2Br4 octahedra, and a faceface with one CaC2Br3N octahedra. The corner-sharing octahedra tilt angles range from 1–80°. Both Ca–C bond lengths are 2.58 Å. There are a spread of Ca–Br bond distances ranging from 2.95–3.12 Å. In the second Ca2+ site, Ca2+ is bonded to one C4-, two equivalent N3-, and three equivalent Br1- atoms to form distorted CaCBr3N2 octahedra that share corners with four CaC2Br4 octahedra and edges with eight CaC2Br3N octahedra. The corner-sharing octahedra tilt angles range from 4–94°. The Ca–C bond length is 2.59 Å. Both Ca–N bond lengths are 2.42 Å. There are one shorter (3.06 Å) and two longer (3.09 Å) Ca–Br bond lengths. In the third Ca2+ site, Ca2+ is bonded to two equivalent C4-, one N3-, and three Br1- atoms to form a mixture of distorted corner, edge, and face-sharing CaC2Br3N octahedra. The corner-sharing octahedra tilt angles range from 1–94°. Both Ca–C bond lengthsmore »
