| Abstract | ||
| Tin, selenium and bismuth metal complexes containing Schiff bases ligands derived from ortho-benzaldehyde, dimethyl ketone, diethyl ketone and di(o-aminophenyl) disulphide have been prepared from the direct reaction of Schiff base and metals in 1:2 molar ratio to give: Sn(SC6H4N=CHC6H4OCH3-o)4, Sn(SC6H4N=C(CH3)2)4, Sn(SC6H4N=C(CH2CH3)2)4, Bi(SC6H4N=CHC6H4OCH3-o)3, Bi(SC6H4N=C(CH3)2)3, SC6H4N=C(CH2CH3)2)3, Se(SC6H4N=CHC6H4O CH3-o)4, Se(SC6H4N=C(CH3) 2)4 and Se(SC6H4N=C(CH2CH3)2)4. The reaction of the above metals with a mixture of iodine and Schiff bases give in (1:1:3) molar ratio the compounds SnI(SC6H4N=CHC6H4OCH3-o)3, SnI(SC6H4N=C(CH3)2)3, SnI(SC6H4N=C(CH2CH3)2)3, BiI(SC6H4N=CH-C6H4OCH3-o)2, BiI(SC6H4N=C(CH3)2)2, BiI(SC6H4N=C(CH2CH3)2)2, SeI(SC6H4N=CHC6H4 OCH3-o)3, SeI(SC6H4N=C(CH3)2)3 and SeI(SC6H4N=C(CH2CH3 )2)3. The compounds were characterized by microanalysis, infrared, UV/Visible spectroscopy and conductivity measurement. | ||
