Crystallography in Latin America: a vibrant community
Edited by Maria Rosales-Hoz and Renata Diniz
The growth of the number of articles published by Latin American researchers has been important in recent years. Part of this growth is represented by structural chemistry papers. This special issue of Acta Crystallographica Section C will help to give visibility to the work carried out by the crystallographic communities in these countries and will coincide with the Sixth Latin American Crystallographic Association (LACA) Meeting.

The diethyl N,N′-(1,3-phenylene)dicarbamate–theophylline (1–TEO) complex was obtained by mechanochemistry involving the conformational change of one of the ethyl carbamate groups of 1 from the endo conformation to the exo conformation to allow the formation of intermolecular interactions.

A series of compounds were synthesized from a 1:2 mixture of a metal and a terpyridine (TPY) ligand, with the general formula [M(R-TPY)2](ClO4)2 (where M = Co2+, Fe2+, Mn2+ and Ni2+, and R-TPY = Ph-TPY, ClPh-TPY and MeOPh-TPY). All compounds were characterized spectroscopically and three, [Ni(Ph-TPY)2](ClO4)2, [Mn(MeOPh-TPY)2](ClO4)2 and [Mn(Ph-TPY)2](ClO4)2, were determinated by single-crystal X-ray diffraction.

Using a cocrystal of a molecule that does not crystallize, we reveal that π–π interactions between aromatic rings are present with only two F atoms in the aromatic ring.
