SbH3 is alpha bismuth trifluoride structured and crystallizes in the tetragonal I4/mmm space group. Sb(1) is bonded to four equivalent H(2) and eight equivalent H(1) atoms to form a mixture of distorted face, corner, and edge-sharing SbH12 cuboctahedra. There are two inequivalent H sites. In the first H site, H(1) is bonded to four equivalent Sb(1) atoms to form a mixture of distorted corner and edge-sharing HSb4 tetrahedra. In the second H site, H(2) is bonded in a square co-planar geometry to four equivalent Sb(1) atoms.
