Materials Data on Ta4SiTe4 by Materials Project

Kristin Persson
Ta4SiTe4 crystallizes in the orthorhombic Pbam space group. The structure is one-dimensional and consists of two Ta4SiTe4 ribbons oriented in the (1, 0, 0) direction. there are two inequivalent Ta3+ sites. In the first Ta3+ site, Ta3+ is bonded to two equivalent Si4- and four Te2- atoms to form a mixture of distorted edge, face, and corner-sharing TaSi2Te4 octahedra. The corner-sharing octahedra tilt angles range from 40–69°. Both Ta–Si bond lengths are 2.60 Å. There...
