Materials Data on RbYTe2 by Materials Project
RbYTe2 is H-Phase structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Rb1+ is bonded to six equivalent Te2- atoms to form distorted RbTe6 pentagonal pyramids that share corners with six equivalent YTe6 octahedra, edges with six equivalent YTe6 octahedra, and edges with six equivalent RbTe6 pentagonal pyramids. The corner-sharing octahedral tilt angles are 11°. All Rb–Te bond lengths are 3.67 Å. Y3+ is bonded to six equivalent Te2- atoms to form YTe6 octahedra that share corners with six equivalent RbTe6 pentagonal pyramids, edges with six equivalent YTe6 octahedra, and edges with six equivalent RbTe6 pentagonal pyramids. All Y–Te bond lengths are 3.12 Å. Te2- is bonded to three equivalent Rb1+ and three equivalent Y3+ atoms to form a mixture of edge, face, and corner-sharing TeRb3Y3 octahedra. The corner-sharing octahedra tilt angles range from 0–42°.
