Abstract

K2AgIn3Se6 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. there are two inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a 7-coordinate geometry to seven Se2- atoms. There are a spread of K–Se bond distances ranging from 3.38–3.97 Å. In the second K1+ site, K1+ is bonded in a 7-coordinate geometry to seven Se2- atoms. There are a spread of K–Se bond distances ranging from 3.39–3.97 Å. Ag1+ is bonded to four Se2- atoms to form AgSe4 tetrahedra that share corners with eight InSe4 tetrahedra. There are two shorter (2.64 Å) and two longer (2.68 Å) Ag–Se bond lengths. There are four inequivalent In3+ sites. In the first In3+ site, In3+ is bonded to four Se2- atoms to form InSe4 tetrahedra that share corners with two equivalent AgSe4 tetrahedra and corners with four InSe4 tetrahedra. There are a spread of In–Se bond distances ranging from 2.62–2.64 Å. In the second In3+ site, In3+ is bonded to four Se2- atoms to form InSe4 tetrahedra that share corners with four equivalent AgSe4 tetrahedra and corners with four InSe4 tetrahedra. There are two shorter (2.62 Å) and two longer (2.65 Å) In–Se bond lengths. In themore »« less
