Two new tris-chelate-complexes have been synthesized and characterized with elemental and spectroscopic methods. IR and thermal studies correlate with the structures of the complex in the solid state. The structure of [Cu(en)(phen)2] was determined with X-ray data using single crystal X-ray diffractometer while the molecular structure of [Cu(en) (phen)2] 2Br - 2Phen·8H2O was deduced from the used characterization methods. [Cu(en)(phen)2]· crystallizes as orthorhombic with space group Pbcn. Both complexes have distorted octahedral geometry. Microbial activities of these complexes against Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Streptoccocus pyogeneous, Candida albicans, and Aspergillus niger were also reported.
