Materials Data on K2(CuTe)5 by Materials Project
Abstract
K2(CuTe)5 is alpha bismuth trifluoride-derived structured and crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. K1+ is bonded in a body-centered cubic geometry to eight Te2- atoms. There are a spread of K–Te bond distances ranging from 3.59–3.78 Å. There are three inequivalent Cu+1.60+ sites. In the first Cu+1.60+ site, Cu+1.60+ is bonded to four Te2- atoms to form a mixture of edge and corner-sharing CuTe4 tetrahedra. There are two shorter (2.57 Å) and two longer (2.60 Å) Cu–Te bond lengths. In the second Cu+1.60+ site, Cu+1.60+ is bonded to four Te2- atoms to form a mixture of edge and corner-sharing CuTe4 tetrahedra. There are two shorter (2.61 Å) and two longer (2.66 Å) Cu–Te bond lengths. In the third Cu+1.60+ site, Cu+1.60+ is bonded to four Te2- atoms to form a mixture of edge and corner-sharing CuTe4 tetrahedra. There are a spread of Cu–Te bond distances ranging from 2.65–2.74 Å. There are three inequivalent Te2- sites. In the first Te2- site, Te2- is bonded in a 8-coordinate geometry to four equivalent K1+ and four Cu+1.60+ atoms. In the second Te2- site, Te2- is bonded in a 8-coordinate geometry to four equivalent K1+ and four Cu+1.60+ atoms.more »
