Materials Data on NaMnTe2 by Materials Project
NaMnTe2 crystallizes in the trigonal P3m1 space group. The structure is three-dimensional. Na1+ is bonded to six Te2- atoms to form NaTe6 octahedra that share corners with six equivalent MnTe4 tetrahedra, edges with six equivalent NaTe6 octahedra, and edges with three equivalent MnTe4 tetrahedra. There are three shorter (3.18 Å) and three longer (3.35 Å) Na–Te bond lengths. Mn3+ is bonded to four Te2- atoms to form MnTe4 tetrahedra that share corners with six equivalent NaTe6 octahedra, corners with six equivalent MnTe4 tetrahedra, and edges with three equivalent NaTe6 octahedra. The corner-sharing octahedra tilt angles range from 18–51°. There are one shorter (2.53 Å) and three longer (2.73 Å) Mn–Te bond lengths. There are two inequivalent Te2- sites. In the first Te2- site, Te2- is bonded in a rectangular see-saw-like geometry to three equivalent Na1+ and one Mn3+ atom. In the second Te2- site, Te2- is bonded to three equivalent Na1+ and three equivalent Mn3+ atoms to form distorted edge-sharing TeNa3Mn3 octahedra.
