InSb2 is Cyanogen Chloride-derived structured and crystallizes in the orthorhombic Pmmm space group. The structure is zero-dimensional and consists of one InSb2 cluster. In3+ is bonded in a linear geometry to two equivalent Sb+1.50- atoms. Both In–Sb bond lengths are 2.70 Å. Sb+1.50- is bonded in a single-bond geometry to one In3+ atom.
Ba(InSb2)2 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Ba2+ is bonded in a 9-coordinate geometry to nine Sb+1.50- atoms. There are a spread of Ba–Sb bond distances ranging from 3.61–3.85 Å. There are two inequivalent In2+ sites. In the first In2+ site, In2+ is bonded to four Sb+1.50- atoms to form corner-sharing InSb4 tetrahedra. There are a spread of In–Sb bond distances ranging from 2.83–2.90 Å. In the second In2+ site, In2+ is bonded to four Sb+1.50- atoms to form corner-sharing InSb4 tetrahedra. There are three shorter (2.91 Å) and one longer (2.96 Å) In–Sb bond lengths. There are four inequivalent Sb+1.50- sites. In the first Sb+1.50- site, Sb+1.50- is bonded to three equivalent Ba2+ and three In2+ atoms to form distorted edge-sharing SbBa3In3 octahedra. In the second Sb+1.50- site, Sb+1.50- is bonded in a 6-coordinate geometry to three equivalent Ba2+, one In2+, and two equivalent Sb+1.50- atoms. Both Sb–Sb bond lengths are 2.99 Å. In the third Sb+1.50- site, Sb+1.50- is bonded in a 1-coordinate geometry to two equivalent Ba2+, one In2+, and four Sb+1.50- atoms. Both Sb–Sb bond lengths are 3.41 Å. In the fourth Sb+1.50- site, Sb+1.50- is bonded in a distorted see-saw-like geometry to one Ba2+, three In2+, and two equivalent Sb+1.50- atoms.
