Self-assembly of new cobalt complexes based on [Co (SCN)], synthesis, empirical, antioxidant activity, and quantum theory investigations.

The cobalt (II) complexes have been synthesized from the reaction of the cationic entities (3,4-dimethylaniline (1) and histamine (2)) with metallic salt CoCl⋅6HO and thiocyanate ion (SCN) as a ligand in HO/ethanolic solution and processing by the evaporation crystal growth method at room temperature to get crystals. The synthesized complex has been fully characterized by single-crystal X-ray diffraction. UV-Visible, FTIR spectroscopy, TGA analysis, and DFT circulations were also performed.
