Abstract

Ho2Mo3Si4 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Ho3+ is bonded to seven Si4- atoms to form distorted HoSi7 pentagonal bipyramids that share corners with four equivalent MoSi6 octahedra, corners with six equivalent HoSi7 pentagonal bipyramids, corners with five equivalent MoSi6 pentagonal pyramids, edges with three equivalent HoSi7 pentagonal bipyramids, edges with two equivalent MoSi6 pentagonal pyramids, faces with two equivalent MoSi6 octahedra, faces with two equivalent HoSi7 pentagonal bipyramids, and faces with four equivalent MoSi6 pentagonal pyramids. The corner-sharing octahedra tilt angles range from 44–51°. There are a spread of Ho–Si bond distances ranging from 2.81–3.04 Å. There are two inequivalent Mo+3.33+ sites. In the first Mo+3.33+ site, Mo+3.33+ is bonded to six Si4- atoms to form MoSi6 octahedra that share corners with four equivalent MoSi6 octahedra, corners with eight equivalent HoSi7 pentagonal bipyramids, corners with six equivalent MoSi6 pentagonal pyramids, faces with four equivalent HoSi7 pentagonal bipyramids, and faces with four equivalent MoSi6 pentagonal pyramids. The corner-sharing octahedral tilt angles are 51°. There are a spread of Mo–Si bond distances ranging from 2.66–2.70 Å.
