TLDR
In this article, the crystal structures of the tellurium(II) metalloorganic complexes have been determined, formed by the reaction of 1 with Ph3CSH(1 : 2 equivalents).Abstract:
Condensation of the highly reactive complex [{Te(NMe2)2}∞]1, prepared by the reaction of TeCl4 and Li[NMe2](1 : 4 equivalents), with various organic acids has been used as a route to tellurium(II) metalloorganic complexes. The crystal structures of 1 and of Te(SCPh3)22, formed by the reaction of 1 with Ph3CSH(1 : 2 equivalents), have been determined.read more

A survey of tellurium-centered secondary-bonding supramolecular synthons
TL;DR: The structural motifs assembled in these systems fall within eight general categories, from single to multiple-bonded supramolecular synthons as mentioned in this paper, and the overall structures assembled by the most important tellurium-based SISs and prospects for their application in crystal engineering are discussed.

The effect of steric hindrance on the association of telluradiazoles through Te-N secondary bonding interactions
TL;DR: In this article, DFT calculations were used to compare the magnitude of steric repulsion to the strength of secondary bonding interactions (SBIs) in the (Te−N)2 supramolecular synthon to explain or predict the supramerolecular structures assembled by two derivatives of the 1,2,5-telluradiazole ring.

The Many Facets of Chalcogen Bonding: Described by Vibrational Spectroscopy.
TL;DR: It is described for the first time a symmetric chalcogen-bonded homodimer stabilized by a charge transfer from a lone pair orbital into a π* orbital, which is shown for 1,2,5-telluradiazole dimers.

Crystal handling at low temperatures
Thomas Kottke,Dietmar Stalke +1 more
TL;DR: In this paper, the cooling of a crystal in combination with the use of a protecting oil facilitates the handling and transfer to a diffractometer of even very sensitive material, and the method is explained and the required device is described in this work.
