Materials Data on RbHS by Materials Project
RbSH crystallizes in the monoclinic C2 space group. The structure is two-dimensional and consists of two RbSH sheets oriented in the (1, 0, 0) direction. Rb1+ is bonded in a 1-coordinate geometry to two equivalent H1+ atoms. There are one shorter (2.85 Å) and one longer (3.15 Å) Rb–H bond lengths. H1+ is bonded in a 4-coordinate geometry to two equivalent Rb1+ and two equivalent S2- atoms. Both H–S bond lengths are 1.69 Å. S2- is bonded in a distorted linear geometry to two equivalent H1+ atoms.
