Materials Data on Ca4MgCo(AsO5)4 by Materials Project
Abstract
Ca4MgCo(AsO5)4 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are two inequivalent Ca sites. In the first Ca site, Ca is bonded in a 8-coordinate geometry to eight O atoms. There are a spread of Ca–O bond distances ranging from 2.33–2.77 Å. In the second Ca site, Ca is bonded in a 7-coordinate geometry to eight O atoms. There are a spread of Ca–O bond distances ranging from 2.32–2.98 Å. Mg is bonded to six O atoms to form MgO6 octahedra that share corners with four equivalent AsO4 tetrahedra. There are a spread of Mg–O bond distances ranging from 2.08–2.16 Å. Co is bonded to six O atoms to form distorted CoO6 octahedra that share corners with four equivalent AsO4 tetrahedra. There are a spread of Co–O bond distances ranging from 1.71–2.33 Å. There are two inequivalent As sites. In the first As site, As is bonded to four O atoms to form AsO4 tetrahedra that share corners with two equivalent MgO6 octahedra. The corner-sharing octahedra tilt angles range from 57–58°. There are a spread of As–O bond distances ranging from 1.71–1.74 Å. In the second As site, As is bonded to four O atoms tomore »
