Materials Data on Ga2TeS2 by Materials Project
Ga2TeS2 crystallizes in the tetragonal I4_1md space group. The structure is three-dimensional. Ga3+ is bonded to one Te2- and three equivalent S2- atoms to form a mixture of distorted edge and corner-sharing GaTeS3 tetrahedra. The Ga–Te bond length is 2.59 Å. There are one shorter (2.32 Å) and two longer (2.37 Å) Ga–S bond lengths. Te2- is bonded in a water-like geometry to two equivalent Ga3+ atoms. S2- is bonded in a distorted trigonal non-coplanar geometry to three equivalent Ga3+ atoms.
