Abstract

K(Ti3Se4)4 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. K1+ is bonded in a distorted hexagonal planar geometry to six Se2- atoms. All K–Se bond lengths are 3.41 Å. There are six inequivalent Ti+2.58+ sites. In the first Ti+2.58+ site, Ti+2.58+ is bonded to six Se2- atoms to form a mixture of face, edge, and corner-sharing TiSe6 octahedra. The corner-sharing octahedra tilt angles range from 42–51°. There are a spread of Ti–Se bond distances ranging from 2.57–2.67 Å. In the second Ti+2.58+ site, Ti+2.58+ is bonded to six Se2- atoms to form a mixture of face, edge, and corner-sharing TiSe6 octahedra. The corner-sharing octahedra tilt angles range from 43–51°. There are a spread of Ti–Se bond distances ranging from 2.56–2.68 Å. In the third Ti+2.58+ site, Ti+2.58+ is bonded to six Se2- atoms to form a mixture of face, edge, and corner-sharing TiSe6 octahedra. The corner-sharing octahedra tilt angles range from 42–51°. There are a spread of Ti–Se bond distances ranging from 2.56–2.67 Å.
