The anion in the crystal structure of the new Zintl phase Cs5Sb8 synthesized from the elements (monoclinic, space group P21/c, a = 724.4(2)pm, b = 1135.2(3)pm, c = 2750.9(8)pm, β = 96.663(5)°, Z = 4) consists of two and three bonded Sb atoms, which are connected to form puckered nets with 5 and 28 membered rings. β-CsSb (monoclinic, space group P21/c, a = 1519.4(3) pm, b = 734.0(2) pm, c = 1432.2(2) pm, β = 113.661(3)°, Z = 4) crystallizes with a superstructure of the LiAs structure type. As in the α phase (NaP type), twobonded Sb- atoms form neary ideal 41 screx chains. In contrast to the α phase the helices have opposite chirality.
