phenylbutan-1-one have been reported . The analytical result suggests an octahedral geometry for the Co(II) complex. The IR Spectrum of the ligands showed a band at 3479 cm -1 due to stretching vibration of the phenolic hydroxyl group. The absorptions at 3076 (Ar-CH), 2981(Aliphatic CH), 1605 (C=N), 1543 and 1470(C=C), 1288 and 1241(C-O) cm -1 . In the spectrum of the cobalt complex the broad band at 3479 cm -1 was absent which is an indication of the deprotonation of the phenolic group and coordination of the oxygen atom to the central metal ion. Also, there was a decrease in wavenumber for the bands initially observed within 1601-1584cm -1 due to the participation of nitrogen atom of the azomethine in coordination to the central metal ion. The Uv spectrum of the ligand gave bands at 329, 339 and 378nm were assigned to ππ*, π-π* and n-π* transitions respectively. These bands were observed at 318 (π-π*), 357(π-π*), 377 (n-π*) in the UV of the cobalt complex. This visible spectrum of the complex gave bands at 406, 609 and 682 nm which were assigned to 4 T1g (F) → 4 T1g (P), 4 T1g (F) → 4 A2g (F) and 4 T1g (F) → 4 T2g (F) transitions respectively, confirming the formation of the metal complex. The cobalt complex adopted a square planar geometry .
