Materials Data on Sr2MoO4 by Materials Project
Sr2MoO4 is (La,Ba)CuO4 structured and crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Sr2+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Sr–O bond distances ranging from 2.41–2.85 Å. Mo4+ is bonded to six O2- atoms to form corner-sharing MoO6 octahedra. The corner-sharing octahedral tilt angles are 0°. There are four shorter (2.01 Å) and two longer (2.13 Å) Mo–O bond lengths. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to five equivalent Sr2+ and one Mo4+ atom to form distorted OSr5Mo octahedra that share corners with seventeen OSr5Mo octahedra, edges with eight equivalent OSr5Mo octahedra, and faces with four equivalent OSr4Mo2 octahedra. The corner-sharing octahedra tilt angles range from 0–56°. In the second O2- site, O2- is bonded to four equivalent Sr2+ and two equivalent Mo4+ atoms to form distorted OSr4Mo2 octahedra that share corners with fourteen OSr5Mo octahedra, edges with two equivalent OSr4Mo2 octahedra, and faces with eight OSr5Mo octahedra. The corner-sharing octahedra tilt angles range from 0–56°.
