Isomeric icosaboranes B₂₀H₂₆: the synchrotron structure of 1,1′-bis­(nido-decaboranyl)

An isomer of B₂₀H₂₆, isolated from the autolysis of nido-B₁₀H₁₄ in a silent electrical discharge, is shown to be the title compound 1,1′-bis(nido-decaboranyl). The mol­ecule has crystallographic inversion symmetry and a long intercage B—B bond of 1.704 (3) Å.

Potassium thio­cyanate argentates: K₃[Ag(SCN)₄], K₄[Ag₂(SCN)₆] and K[Ag(SCN)₂]

The Ag⁺ ions in the title compounds are tetrahedrally coordinated by the S atoms of four thiocyanate groups, which act as terminal or 1,1-μ-bridging ligands. The anions in K[Ag(SCN)₂] form a two-dimensional polymeric network containing Ag₂S₂ and Ag₆S₆ rings.

Monoclinic superstructure of SrMgF₄ with perovskite-type slabs

The monoclinic superstructure of Ce-doped SrMgF₄ can be described as a stack of perovskite-type slabs in which MgF₆ octahedra are rotated in a complicated manner. Sr atoms are shifted from ideal positions to fit in the space formed by the six MgF₆ octahedra of one slab and one MgF₆ octahedron of a neighbouring slab.
