Abstract

Dy3FeGaS7 crystallizes in the hexagonal P6_3 space group. The structure is three-dimensional. Dy3+ is bonded to seven S2- atoms to form distorted DyS7 pentagonal bipyramids that share a cornercorner with one FeS6 octahedra, corners with six equivalent DyS7 pentagonal bipyramids, corners with two equivalent GaS4 tetrahedra, an edgeedge with one FeS6 octahedra, edges with four equivalent DyS7 pentagonal bipyramids, an edgeedge with one GaS4 tetrahedra, and a faceface with one FeS6 octahedra. The corner-sharing octahedral tilt angles are 22°. There are a spread of Dy–S bond distances ranging from 2.72–2.97 Å. Fe2+ is bonded to six equivalent S2- atoms to form FeS6 octahedra that share corners with three equivalent DyS7 pentagonal bipyramids, edges with three equivalent DyS7 pentagonal bipyramids, faces with two equivalent FeS6 octahedra, and faces with three equivalent DyS7 pentagonal bipyramids. There are three shorter (2.34 Å) and three longer (2.39 Å) Fe–S bond lengths. Ga3+ is bonded to four S2- atoms to form GaS4 tetrahedra that share corners with six equivalent DyS7 pentagonal bipyramids and edges with three equivalent DyS7 pentagonal bipyramids. There are one shorter (2.25 Å) and three longer (2.27 Å) Ga–S bond lengths. There are three inequivalent S2- sites. In the first S2- site,more »« less
