Abstract: Synthesis and single-crystal X-ray structure determination of the new antimonide oxide, Ba5Cd2Sb4O2 are reported. Ba5Cd2Sb4O2 crystallizes in the monoclinic space group C2/m (No. 12) with unit cell parameters: a = 17.247(7) Å, b = 4.9279(18) Å, c = 12.240(5) Å, and β = 132.558(4)°; Z = 2. Its crystal structure can be described as a polyanionic [Cd2Sb4]6– sub-lattice made up of fused CdSb4 tetrahedra, stacked between puckered slabs of oxo-anions, O2–, and Ba2+ cations. This structure can also be described as a “double-salt”, i.e., a structure composed of fragments from the Zintl phase Ba3Cd2Sb4 intercalated by two BaO-like moieties. The topological similarities between the structures of these compounds are discussed.
