The organization and stability of coordination compounds could be correlated to structural features, as the number and nature of ligands coordinated to the metallic ions and with noncovalent interactions established between the ligands and with crystallization solvents. The present work evaluated the influence of the pre-ligands 2,6-dihydroxybenzoic acid (Hdhb), benzoic acid (Hbzt), oxalic acid (H2ox), and 2,2' bipyridine (bipi), capable to perform noncovalent interactions, in its reactivity to copper(II), cobalt(II) and manganese(II) salts. For each metallic ion, and reaction condition were evaluated with different combinations of ligands, producing 10 different structures characterized by single crystal XRD. Among them, the complexes [Cu2...
