Materials Data on SbH3 by Materials Project
SbH3 is alpha bismuth trifluoride structured and crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Sb3- is bonded to twelve H1+ atoms to form a mixture of distorted face, edge, and corner-sharing SbH12 cuboctahedra. There are eight shorter (2.30 Å) and four longer (2.40 Å) Sb–H bond lengths. There are two inequivalent H1+ sites. In the first H1+ site, H1+ is bonded to four equivalent Sb3- atoms to form a mixture of distorted edge and corner-sharing HSb4 tetrahedra. In the second H1+ site, H1+ is bonded in a square co-planar geometry to four equivalent Sb3- atoms.
