Abstract

Ni4CuO5 is Caswellsilverite-like structured and crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. there are two inequivalent Ni2+ sites. In the first Ni2+ site, Ni2+ is bonded to six O2- atoms to form NiO6 octahedra that share corners with six NiO6 octahedra, edges with four equivalent CuO6 octahedra, and edges with eight NiO6 octahedra. The corner-sharing octahedra tilt angles range from 0–1°. All Ni–O bond lengths are 2.12 Å. In the second Ni2+ site, Ni2+ is bonded to six O2- atoms to form NiO6 octahedra that share a cornercorner with one CuO6 octahedra, corners with five NiO6 octahedra, and edges with twelve NiO6 octahedra. The corner-sharing octahedral tilt angles are 0°. There are one shorter (2.10 Å) and five longer (2.12 Å) Ni–O bond lengths. Cu2+ is bonded to six O2- atoms to form CuO6 octahedra that share corners with two equivalent NiO6 octahedra, corners with four equivalent CuO6 octahedra, edges with four equivalent CuO6 octahedra, and edges with eight equivalent NiO6 octahedra. The corner-sharing octahedral tilt angles are 0°. There are four shorter (2.12 Å) and two longer (2.14 Å) Cu–O bond lengths. There are four inequivalent O2- sites.
