Title: Materials Data on K(Nb3Te4)2 by Materials Project

Abstract

K(Nb3Te4)2 crystallizes in the trigonal P-3 space group. The structure is three-dimensional. K1+ is bonded in a distorted hexagonal planar geometry to six equivalent Te2- atoms. All K–Te bond lengths are 3.51 Å. Nb+2.50+ is bonded to six Te2- atoms to form a mixture of distorted face, edge, and corner-sharing NbTe6 octahedra. The corner-sharing octahedra tilt angles range from 46–56°. There are a spread of Nb–Te bond distances ranging from 2.79–3.06 Å. There are two inequivalent Te2- sites. In the first Te2- site, Te2- is bonded to six equivalent Nb+2.50+ atoms to form distorted face-sharing TeNb6 pentagonal pyramids. In the second Te2- site, Te2- is bonded in a 5-coordinate geometry to one K1+ and four equivalent Nb+2.50+ atoms.
