Materials Data on Rb2TaAgS2 by Materials Project
Rb2TaAgS2 crystallizes in the orthorhombic Fddd space group. The structure is two-dimensional and consists of four Rb2TaAgS2 sheets oriented in the (0, 0, 1) direction. Rb is bonded in a 4-coordinate geometry to one Ag and three equivalent S atoms. The Rb–Ag bond length is 3.32 Å. There are a spread of Rb–S bond distances ranging from 3.06–3.15 Å. Ta is bonded in a distorted linear geometry to two equivalent Ag and two equivalent S atoms. Both Ta–Ag bond lengths are 2.94 Å. Both Ta–S bond lengths are 2.31 Å. Ag is bonded in a 8-coordinate geometry to two equivalent Rb and two equivalent Ta atoms. S is bonded in a 4-coordinate geometry to three equivalent Rb and one Ta atom.
