Resumo

The study of transition metal complexes with bidentate ligands is gaining prominence due to its potential for biological application. Therefore, studying these complexes' structure, thermal stability, and intermolecular interactions is crucial to understanding their properties and assessing their potential use in pharmaceutical drugs. From this location, the tris(1,10-phenanthroline)-cobalt(III) triperchlorate dihydrate complex was synthesized by the slow solvent evaporation technique in 20 days, with a prismatic shape and orange coloration. The structure was confirmed by the powder XRPD technique combined with refinement by the Rietveld method at room temperature, with formula [Co(C12H8N2)3](ClO4)3.2H2O, monoclinic structure, space group C2/C. From the differential scanning calorimetry (DSC) analysis in the temperature range between 300 K and 750 K, we observed an exothermic peak at 625 K that indicates a total enthalpy involved in the process of 1313.07 kJ/mol, referring to the vaporization of uncoordinated water and the (ClO4-)3 molecule, indicating that the material has good thermal stability. The Hirshfeld surface analyses demonstrated that the main intermolecular interactions involve the atoms of H...H (34.5%), H...O/O...H (34.4%), H...C/C...H (15.9%), C...O/O...C (12.8%) e C...C (1.8%). Therefore, the results obtained demonstrate that the material has good thermal stability and potential for carrying out intermolecularinteractions that allow new characterizations in order to investigate its possible application in biological activities.
