β-Rubidium antimonide, Rb₄Sb₄

β-RbSb crystallizes with the LiAs structure type. As in the α phase (NaP type), Sb⁻ forms approximate 4₁ helical chains (2₁ crystallographic symmetry), with Sb—Sb distances of 2.838 (1) and 2.862 (1) Å. In contrast to the α phase, the helices have different chirality.

Barium antimonide oxide, Ba₃Sb₂O

The antimonide oxide Ba₃Sb₂O consists of discrete [Sb₂]⁴⁻ and O²⁻ anions, and crystallizes with a new structure type. The Sb—Sb distances are comparable to those known from electron-precise zintl phases and the tetrahedral coordination of the O²⁻ anion is also observed in some other Ba-rich metallide oxides.

Pentapotassium dodecatungsto­borate(III) hexadecahydrate

The anion of the title compound has the α-Keggin structure, with a central tetrahedrally coordinated B^III atom surrounded by four groups of three edge-sharing octahedra (W₃O₁₃ subunits) which are linked in turn to each other and to the central BO₄ tetrahedron by shared O atoms at the vertices.

KSbO(Ge_0.32Si_0.68)O₄, a KTP isomorph

KSbO(Ge_0.32Si_0.68)O₄ is isomorphic with KTP, i.e. KTiOPO₄. It contains mixed (Ge/Si)O₄ tetrahedra with the same distribution in each independent tetrahedron and split potassium-cation positions. The crystal is paraelectric (space group Pnan) at room temperature.
