K2TiS3 is Krennerite-derived structured and crystallizes in the monoclinic C2/c space group. K(1) is bonded in a 6-coordinate geometry to two equivalent S(1) and four equivalent S(2) atoms. Ti(1) is bonded to one S(1) and four equivalent S(2) atoms to form distorted edge-sharing TiS5 trigonal bipyramids. There are two inequivalent S sites. In the first S site, S(1) is bonded in a 1-coordinate geometry to four equivalent K(1) and one Ti(1) atom. In the second S site, S(2) is bonded to four equivalent K(1) and two equivalent Ti(1) atoms to form a mixture of distorted face, corner, and edge-sharing SK4Ti2 octahedra. The corner-sharing octahedral tilt angles range from 31-48°.
K2TiS3 is Krennerite-derived structured and crystallizes in the monoclinic C2/c space group. K(1) is bonded in a 6-coordinate geometry to two equivalent S(1) and four equivalent S(2) atoms. There is one shorter (3.24 Å) and one longer (3.62 Å) K(1)-S(1) bond length. There are a spread of K(1)-S(2) bond distances ranging from 3.18-3.25 Å. Ti(1) is bonded to one S(1) and four equivalent S(2) atoms to form distorted edge-sharing TiS5 trigonal bipyramids. The Ti(1)-S(1) bond length is 2.21 Å. There are two shorter (2.39 Å) and two longer (2.42 Å) Ti(1)-S(2) bond lengths. There are two inequivalent S sites. In the first S site, S(1) is bonded in a 1-coordinate geometry to four equivalent K(1) and one Ti(1) atom.
