The synthesis of coordination complexes is presently of increased interest because of their potential application in catalysis [1], adsorption, storage, molecular recognition, fluorescence, sensors, magnetism...etc [2]. Moreover, they play an important role in the medical and pharmaceutical fields. They show potential applications and properties such as antibacterial, antifungal, anti-tumor [3-4] and anti-inflammatory [5] activities.

In previous works, we reported the synthesis of new metal complex (Ni^II), as well as the characterization by IR, UV-Vis and electrochemical study. Further support for the structure was derived from elemental analysis.

The antibacterial activities of the metal were investigated on gram positive Staphylococcus aureus (ATCC25923) and gram negative bacteria Pseudomonas aeroginosa (ATCC27853), by disc diffusion method.
