Materials Data on Ge5(Te4As)2 by Materials Project

Kristin Persson
Ge5(AsTe4)2 is Caswellsilverite-like structured and crystallizes in the trigonal P-3m1 space group. The structure is two-dimensional and consists of one Ge5(AsTe4)2 sheet oriented in the (0, 0, 1) direction. there are three inequivalent Ge4+ sites. In the first Ge4+ site, Ge4+ is bonded to six equivalent Te2- atoms to form a mixture of edge and corner-sharing GeTe6 octahedra. The corner-sharing octahedral tilt angles are 0°. All Ge–Te bond lengths are 2.99 Å. In the second...
