Alexander B. Sorokin and colleagues at the University of Lyon, France, continue their work on metallophthalocyanines by looking at N-bridged diiron complexes with an Fe–N–Fe core unit.

Having previously discovered these types of compound are capable of the catalytic oxidation of organic substrates (read their earlier paper here), in this Dalton Transactions Hot article Sorokin explains the high reactivity of this species, and how the system can efficiently oxidizing methane at extremely mild conditions.

Dominic Freudenmann and Claus Feldmann from the Karlsruhe Institute of Technology, Germany,  have used an ionic liquid to obtain transparent red crystals of [Bi₃GaS₅]₂[Ga₃Cl₁₀]₂[GaCl₄]₂·S₈.

In this Dalton Transactions Hot article they explain that the cation unit of the crystal [Bi₃GaS₅]²⁺ appears as a (Bi–S–Ga)-heterocubane, and unusually, the anion [Ga₃Cl₁₀]^– is in a star shaped form, with three (GaCl4) tetrahedra sharing a single central chlorine atom. This type of structure is particularly exciting as it has only previously been observed in fluoride complexes.

[Bi₃GaS₅]₂[Ga₃Cl₁₀]₂[GaCl₄]₂·S₈ containing heterocubane-type [Bi₃GaS₅]²⁺, star-shaped [Ga₃Cl₁₀]−, monomeric [GaCl₄]− and crown-like S₈
