Er₅Ni₃Al₃Ge₄: a quaternary variant of the NbCoB type

Er₅Ni₃Al₃Ge₄ is a quaternary ordered variant of the NbCoB type and is described as an inter­growth of Er₃NiAl₃Ge₂ and ErNiGe fragments.

Cu₃(CN)₄(NH₃)₂Hg(CN)₂: a novel inter­penetrating framework formed from Cu^I, Cu^II, Hg^II and cyanide bridges

The crystal structure of Cu₃(CN)₄(NH₃)₂Hg(CN)₂ is a threefold-inter­penetrating structure of three-dimensional frameworks, which are formed from two-dimensional network Cu^I/Cu^II–cyanide complexes, Cu₃(CN)₄(NH₃)₂, connected by rod-like Hg(CN)₂ groups.

NaIn(CrO₄)₂·2H₂O, the first indium(III) member of the kröhnkite family

NaIn(CrO₄)₂·2H₂O represents an unusual member of the family of compounds based on infinite kröhnkite-type chains. It shows an unprecedented octa­hedral coordination of the Na atom.

Sr₂Cu₂TeO₆Br₂: honeycomb layers of copper(II) ions

The layered structure of the title compound is formed by TeO₆ octa­hedra, CuO₅ square pyramids and irregular SrO₄Br₃ polyhedra. The Cu^II ions are arranged to form puckered honeycomb layers.
