Two tetrahedral mononuclear complexes with a general formula
[CoX2(dmphen)](1-2) (where dmphen is 2,9-dimethyl 1,10-phenanthroline and 1 (X=Br), 2 (X=NCS)) have been
synthesized. These complexes are characterized by elemental analysis, IR, UV-visible, TG/DTA and
by X-ray diffraction.The calculated electrostatic potential surface of 2 has shown that the
electrostatic potential values
around sulfur atom is anistropically distributed; the potential values along
C-S bond is less negative -region of S atom. This agrees with the observed geometricalpthan
the corresponding values in the .°arrangement
of C-H…S-C hydrogen bonding interactions, the avg. of H…S-C angle is 81
Antimicrobial properties of cobalt (II) complexes was also assessed. Cobalt
complexes exhibited significant antibacterial activity against different Gram negative and positive
human pathogens. The absorption spectrum of these complexes in acetone was modeled by time-dependent
density functional
theory (TD-DFT).
