Materials Data on Fe2CuAs2(HO5)2 by Materials Project
Abstract
Fe2CuAs2(HO5)2 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. Fe3+ is bonded to six O2- atoms to form FeO6 octahedra that share corners with four equivalent AsO4 tetrahedra, an edgeedge with one FeO6 octahedra, and edges with two equivalent CuO6 octahedra. There are a spread of Fe–O bond distances ranging from 1.94–2.35 Å. Cu2+ is bonded to six O2- atoms to form distorted CuO6 octahedra that share corners with four equivalent AsO4 tetrahedra and edges with four equivalent FeO6 octahedra. There are a spread of Cu–O bond distances ranging from 1.92–2.46 Å. As5+ is bonded to four O2- atoms to form AsO4 tetrahedra that share corners with two equivalent CuO6 octahedra and corners with four equivalent FeO6 octahedra. The corner-sharing octahedra tilt angles range from 36–59°. There are a spread of As–O bond distances ranging from 1.68–1.81 Å. H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 1.00 Å. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to one Fe3+, one Cu2+, and one As5+ atom. In the second O2- site, O2- is bonded in a 1-coordinate geometry to onemore »
