KCd₂[N(CN)₂]₅(H₂O)₄: an enmeshed honeycomb grid

Poly[potassium [diaqua­penta-μ₂-dicyan­amido-dicadmium(II)] dihydrate] contains two-dimensional anionic sheets of {[Cd₂{N(CN)₂}(H₂O)₂]⁻}_n with a modified (6,3)-net (layer group , No. 35). Two sets of equivalent sheets inter­penetrate orthogonally to form a tetragonal enmeshed grid.

New oxyfluoro­tellurates(IV): MTeO₃F (M = Fe^III, Ga^III and Cr^III)

The syntheses and crystal structures of a new series of isomorphous oxyfluoro­tellurates(IV) of trivalent metals Fe, Ga and Cr are described. Contrary to other oxyfluoro­tellurates, these phases are air stable, which is explained by the absence of Te—F bonds in a structure derived from the α-PbO₂ type.

Li₈Cu_12+xAl_6−x (x = 1.16): a new structure type related to Laves phases

Li₈Cu_12+xAl_6−x (x = 1.16) is a new structure type related to the Laves phases MgZn₂, MgCu_1.07Al_0.93 and Mg(Cu_1−xAl_x)₂. The atoms in this inter­metallic structure are found in icosa­hedral (Cu atoms), slightly distorted icosa­hedral and bicapped hexa­gonal anti­prismatic (Al/Cu statistical mixture), and Frank–Kasper and distorted Frank–Kasper polyhedral (Li atoms) environments.

Caesium cis-tetra­chlorido­dioxido­rhenate(VII)

Cs[ReCl₄O₂] consists of cis-tetra­chlorido­dioxido­rhenate(VII) anions and caesium cations. The distorted octa­hedral anion has nearly C_2v symmetry, with a cis arrangement of the oxide ligands.
