COMPLEXES OF Zn(II) AND Cd(II) WITH 1-(FURAN-2-YLMETHYLENE)UREA AND N-(PROPAN-2-YLIDENE)BENZOHYDRAZIDE

Complexes of Zn(II) and Cd(II) with 1-(furan-2-ylmethylene)urea (A) and N-(propan-2-ylidene)benzohydrazide (B) have been synthesized and characterized by IR, UV/Vis spectroscopy, powdered X-ray diffractometry, scanning electron microscopy, conductivity, elemental study and solubility study. The ligands were also characterized by HNMR spectroscopy. The result showed that the ligands acted as bidentate donors coordinating through the azomethine nitrogen and the carbonyl oxygen. The elemental analysis indicates that the complexes of Zn and Cd with A precipitated as ML1 types complex while complexes of B with Zn precipitated as an ML2 type complex. The complex of Cd with B however the not precipitate from solution. The conductivity study also indicates that the complexes A are electrolytes while B complex is a non-electrolyte.
