Isomorphic substitution in molecular crystals and geometry of hypervalent tellurium: comments inspired by a case study of RMeTeI2 and [RMe2Te]+I− (R = Ph, Fc)
Unusual isomorphic substitution in the crystals of [FcMe2Te]+I− with an admixture of Te–I ionized [FcMeTeI+]I− supports the 3c-4e as a general, seamless bonding model for the hypervalent tellurium in both the isolated molecules and crystals.

About this collection
The chemistry of selenium and tellurium is experiencing continuous and exponential growth thanks to its implication in many research fields spanning from fundamental organic/inorganic/bio-chemistry, to material science, biology, pharmacology, medicine, agriculture and environmental science.
The International Conference on the Chemistry of Selenium and Tellurium (ICCST), next year at its 14th edition, has witnessed and supported the growth of this research area since 1971, offering an International forum for discussing cutting-edge results. Interest in the chemistry of these two elements has been sustained by the RSC publishing several reviews and monographs over the past decade.
This thematic web collection on all facets of the chemistry of selenium and tellurium will give an open updated snapshot of the research on these two elements as multidisciplinary science, offering unique opportunities of interactions of researchers working in different areas, and it will celebrate ICCST as recognized platform of discussion.
The collection, Guest Edited by Vito Lippolis and Claudio Santi, will contain papers published in the past 20 years by chemists who have attended ICCST, and new papers published in NJC by the end of 2019.
