Dear Donia Said, we're talking about organometallic compounds when direct metal-carbon (M–C) bonds of some sort (sigma- or pi-bonded) are present. In the case of your ligand (phenyl pyridyl ketoxime) most (if not all) metal complexes are NOT organometallic compounds. A typical example is the copper complex in the attached reference. In this case no M–C bond is present. There could, however, be rare cases in which cyclometalation reactions under formation of M–C bonds might occur.

Since there is no direct metal-carbon bond involvement it is not a organo metallic compound
