ChemInform Abstract: Unusual Inorganic Biradicals: A Theoretical Analysis.

Quantum chemical calculations at the CASSCF level of theory on the O₃‐homologous molecules CX₂^2‐, NX₂^‐, X₃, OX₂, and FX₂⁺ (X: O, S, Se, Te, Po) indicate that the triatomic inorganic biradicals in the FX₂⁺ series have unusually high biradical character.

The paramagnetic compounds [Os₂(OCOR)₄Cl₂] (R = n-C₃H₇, C₂H₇, C₂H₅, CH₂Cl) have been synthesized by reaction of [Os(OCOCH₃)₂Cl]_n with the appropriate acids and the binuclear tetracarboxylate bridged structure confirmed by X-ray analysis for R = n-C₃H₇, (OsOs distance 2.301 Å, cf. the related [Os₂(hp)₄Cl₂](CH₃CN)₂; OsOs, 2.357 Å) (hp = 2-hydroxypyridine anion).     

Inorganic Self-assembly: Going Bio

The use of self-assembly for building complex functional structures is a current topic of interest in supramolecular chemistry. In this context, the use of biomolecule-based building blocks has paved the way for the development of intracellular assemblies. Currently, the potential functionality of such assemblies in biomedical applications is being disclosed. On the other hand, the use of inorganic (metal-based) building blocks is still in its infancy. The construction of inorganic self-assemblies in-bio is particularly challenging and demands great efforts to reach applications. However, the plethora of thinkable advantages related to the use of inorganic self-assembly in living cells must fuel new discoveries in this area. This Concept reviews the current advances, perspectives, and challenges in inorganic self-assembly in living systems.
