Abstract

MnGa2S4 crystallizes in the trigonal R3m space group. The structure is two-dimensional and consists of three MnGa2S4 sheets oriented in the (0, 0, 1) direction. Mn2+ is bonded to four S2- atoms to form MnS4 tetrahedra that share corners with three equivalent GaS6 octahedra and corners with six equivalent MnS4 tetrahedra. The corner-sharing octahedral tilt angles are 61°. There are three shorter (2.33 Å) and one longer (2.44 Å) Mn–S bond lengths. There are two inequivalent Ga3+ sites. In the first Ga3+ site, Ga3+ is bonded to six S2- atoms to form GaS6 octahedra that share corners with three equivalent MnS4 tetrahedra, corners with three equivalent GaS4 tetrahedra, and edges with six equivalent GaS6 octahedra. There are three shorter (2.48 Å) and three longer (2.58 Å) Ga–S bond lengths. In the second Ga3+ site, Ga3+ is bonded to four S2- atoms to form GaS4 tetrahedra that share corners with three equivalent GaS6 octahedra and corners with six equivalent GaS4 tetrahedra. The corner-sharing octahedral tilt angles are 57°. There are one shorter (2.28 Å) and three longer (2.36 Å) Ga–S bond lengths. There are four inequivalent S2- sites. In the first S2- site, S2- is bonded in a trigonal non-coplanar geometrymore »« less
