HOT Article: Microcages with high geometrical symmetry

In this HOT article, Chinese researchers synthesized novel polyhedral 26-facet CuS microcages decorated with unique crystalline structures as building blocks via a facile sacrificial Cu2O templates solution route. Each of the polyhedral 26-facet CuS microcages is constructed of three different structural shells, which are enclosed by three pairs of square mesostructural shells, four pairs of nanotwinned triangular shells, and six pairs of rectangular single crystalline shells. The study should be of great importance for the “bottom-up” assembly of unusual hollow ordering superstructures.

Welcoming new Editorial Board member: Nicola Pinna

We are very pleased to announce the appointment of Professor Nicola Pinna to the CrystEngComm Editorial Board,

Professor Nicola Pinna, based at the University of Aveiro, Portugal, and Seoul National University, Korea, has research interests in the area of nanostructured materials.  His research achievements include work to develop new synthetic approaches to allow a more generalized synthesis strategy to inorganic nanomaterials via a  ‘toolbox’ of well-known chemical reactions which can be used to prepare target nanoparticles using a sequence of predictable synthesis steps.

Nicola Pinna

Professor Nicola Pinna

Nicola  studied physical chemistry at the Université Pierre et Marie Curie in Paris, and received his Ph.D. in 2001. He then moved to the Fritz Haber Institute of the Max Planck Society in Berlin, and a year later, in 2003, moved to the Max Planck Institute of Colloids and Interfaces in Potsdam, followed by a year at the Martin Luther University, Halle-Wittenberg, as an Assistant Professor of Inorganic Chemistry, in 2005. Since 2006 he has been a researcher at the University of Aveiro, and since 2009 has held a joint position at Seoul National University.

In 2011, Nicola Pinna was ranked among the top 100 materials scientists of the past decade by impact.

Unprecedently Short Halogen Bonds

Tetrahedral arrangement of N-iodosuccinimide with tetrafunctional hexamethylenetetramine forming infinite channels along the crystallographic c axis

Supramolecular synthons based on halogen bonding have been identified as excellent tools for the design and synthesis of supramolecular architectures. This growing field in crystal engineering has led to many discoveries of new and exciting intermolecular bonding motifs.

In this advance article, Kari Raatikainen and Kari Rissanen from the University of Jyväskylä report extremely short X···N synthons (where X= Br, I) from the crystal structures of N-haloimides with a series of amines and identify a unique example of a halogen bond based tubular material.

X-ray structure analyses reveal that X···N (X = Br, I) distances range from 2.347 Å to 2.596 Å. These unusually short halogen bond distances suggest an extremely polarized halogen atom, which allows exceptionally large overlap of Van der Waals volumes with the donor atom. The tetrahedral arrangement of N-iodosuccinimide with tetrafunctional hexamethylenetetramine exhibits these very strong halogen bonds, as well as multiple weak C-H···O hydrogen bonds, to form infinite channels with 7.31 Å × 6.74 Å diameter along the crystallographic c axis. The properties of this complex as a porous material are currently under investigation.

Interaction between amines and N-haloimides: a new motif for unprecedentedly short Br···N and I···N halogen bonds

August Crystal Clear: Seeing (nano)stars

This month’s Crystal Clear shows a vanadia star-shaped nanocrystal.

The crystal was made by Sarbajit Banerjee and colleagues at the State University of New York, Buffalo. They were making six-armed nanocrystallites of binary vanadium oxides, and although in this particular image the arms aren’t fully separated, we still thought it was a great looking crystal. They used a new seeded growth strategy that was very successful in making controlled shapes with good monodispersity, and you’ll have to read the full paper to see the complete nanostars!

Vanadium oxides are important in technology, partly because the variety of structures they can form makes them invaluable as host lattices, but also because of their interesting electonic, electrochromic, magnetic and optical properties. Vanadium oxides have consequently been used in batteries, as well as optical applications like laser crystals and switching devices.

This paper was published in Issue 17 of CrystEngComm, and was featured on the front cover, read our earlier blog to find out more.

Read the full article for free to find our more and to see the fully formed star-shaped crystals…
