In this Dalton Transactions Hot article, two new Co^_II/Ln^III complexes are synthesized with 2-amino-isobutyric acid.

The complexes are hetero-heptametallic clusters ( [Co^II₆Ln^III] )with 2-amino-isobutyric acid as the ligand, forming 3d-4f metallic cages in which the Ln^III centre (Ln = Eu, Dy) is encapsulated within a Co^II₆ trigonal prism.

Constantinos J. Milios and co-workers from the University of Crete looked at the optical and magnetic properties of their complexes, and found that one (containing Dysprosium) has the potential to be a single molecule magnet, while the other (containing Europium) exhibited luminescent properties.

In this new Dalton Transactions Hot Article, Macgregor, Welch, Zanello et al. report the synthesis of carboranes substituted with a range of ArF substituents.  The team also describe the results of spectroscopic, computational and (spectro)electrochemical studies for identifying the best ArF substituent to stabilise the new carboranes once reduced.

Supraicosahedral heteroborane chemistry is an area of contemporary interest. Heteroborane clusters with >12 vertices can be challenging to synthesise and can present interesting problems for computational chemists.

Supraicosahedral heteroborane chemistry is important as  such compounds could find valuable applications in a wide range of fields  from bond activation and homogeneous catalysis to medicine.

In this paper, indium(III), antimony(III) and bismuth(III) dihalide complexes with deprotonated, tridentate thio- and selenosemicarbazone ligands have been fully investigated.

An understanding of the chemistry of the thiosemicarbazonato ligand, which is known for its anti tumour and pharmacological properties, is of high importance, and is of special interest to scientists in the field of organoselenium research.

This Perspective article by Shuang Liu, an expert in radiopharmaceuticals, looks at different synthesis methods and applications of  ^99mTc radiotracers.

Liu, based at the School of Health Sciences, Purdue University, USA, brings together both the latest research and the fundamental chemistry of Technetium-99 m. This offers an invaluable insight into nuclear medicine and using techniques such as single photon emission computed tomography (SPECT) and positron emission tomography (PET).
