Materials Data on Na6MnTe4 by Materials Project
Na6MnTe4 crystallizes in the hexagonal P6_3mc space group. The structure is three-dimensional. there are two inequivalent Na1+ sites. In the first Na1+ site, Na1+ is bonded to four Te2- atoms to form distorted NaTe4 tetrahedra that share corners with two equivalent MnTe4 tetrahedra, corners with eight equivalent NaTe4 tetrahedra, and an edgeedge with one MnTe4 tetrahedra. There are a spread of Na–Te bond distances ranging from 3.08–3.24 Å. In the second Na1+ site, Na1+ is bonded in a 5-coordinate geometry to five Te2- atoms. There are a spread of Na–Te bond distances ranging from 3.19–3.55 Å. Mn2+ is bonded to four Te2- atoms to form MnTe4 tetrahedra that share corners with six equivalent NaTe4 tetrahedra and edges with three equivalent NaTe4 tetrahedra. There are three shorter (2.73 Å) and one longer (2.74 Å) Mn–Te bond lengths. There are two inequivalent Te2- sites. In the first Te2- site, Te2- is bonded in a 7-coordinate geometry to six Na1+ and one Mn2+ atom. In the second Te2- site, Te2- is bonded in a 8-coordinate geometry to seven Na1+ and one Mn2+ atom.
