Materials Data on CoAsO5 by Materials Project
Abstract
CoAsO5 crystallizes in the triclinic P-1 space group. The structure is two-dimensional and consists of two CoAsO5 sheets oriented in the (0, 0, 1) direction. In one of the CoAsO5 sheets, there are two inequivalent Co sites. In the first Co site, Co is bonded to six O atoms to form CoO6 octahedra that share corners with five AsO4 tetrahedra and edges with two CoO6 octahedra. There are a spread of Co–O bond distances ranging from 1.67–2.05 Å. In the second Co site, Co is bonded to six O atoms to form CoO6 octahedra that share corners with five AsO4 tetrahedra and edges with two CoO6 octahedra. There are a spread of Co–O bond distances ranging from 1.69–2.11 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 five CoO6 octahedra. The corner-sharing octahedra tilt angles range from 43–58°. There are a spread of As–O bond distances ranging from 1.69–1.78 Å. In the second As site, As is bonded to four O atoms to form AsO4 tetrahedra that share corners with five CoO6 octahedra. The corner-sharing octahedra tilt angles range from 50–60°. Theremore »
