| Abstract | ||
| The reaction of benzil bis(semicarbazone) - BBSCH and other semicarbazone ligands (benzoin semicarbazone - BSH or 2-chlorobenzaldehyde semi- carbazone - CSH or 2-fluorobenzaldehyde semicarba- zone - FSH or furfuraldehyde semicarbazone – FrSH) with ZnSO4.7H2O or ZnCO3 in 1:1:1 molar ratio affords mononuclear complexes of the general formula [Zn(BBSCH)(LH)X] and [Zn(BBSC)(L)] in neutral and basic medium, respectively (where LH= BSH, CSH, FSH or FrSH ; L= deprotonated LH ligands ; BBSC= deprotonated BBSCH ligand ; X=SO42- or CO32-). The coordination of the ligands in the mononuclear complexes seems to occur via the N-azomethine and O-carbonyl groups. The resulted complexes have been characterized physico-chemi- cally, distorted | ||
