MONONUCLEAR COBALT(II) COORDINATION COMPOUNDS OF ACETOHYDRAZONES WITH QUINOLINE CORE Authors: Althobiti HAA and Zabin SA*,
ABSTRACT
This research work aimed at synthesis of some new cobalt coordination compounds using
ligands of acetohydrazone Schiff bases with quinoline core in their structure. Four derivatives of
acetohydrazone ligands were synthesized using 2-(quinolin-8-yloxy) acetohydrazide and
condensed with different aromatic aldehydes. These ligands were used further in preparing
mononuclear Co(II) complexes. The synthesized compounds structures were elucidated by
different analytical methods. Their potential antimicrobial activities were assessed in vitro
against different bacterial and fungal strains. Co(II) coordination compounds showed little
enhancement in the activity against the gram-positive bacterial strains compared to their parent
organic ligands. The compound [Co(HL3)2] was the most active chemical against both grampositive
S. aureus and E. faecalis bacteria.
