Abstract:
Four new nickel(II), zinc(II) and manganese(III) complexes, [NiL] (1), [Zn3L2(OAc)2] (2), [ZnL(CH3OH)] (3) and [MnClL(DMF)] (4), derived from the bis-Schiff base N,N'-bis(4-bromosalicylidene)propane-1,2-diamine (H2L) have been prepared and characterized by spectroscopy methods, as well as single crystal X-ray determination. The Ni atom in the mononuclear nickel complex 1 is in square planar coordination. The outer and inner Zn atoms in the trinuclear zinc complex 2 are in square planar and octahedral coordination, respectively. The Zn atom in the mononuclear zinc complex 3 is in square pyramidal coordination. The Mn atom in the mononuclear manganese complex 4 is in octahedral coordination. Antibacterial activity of the complexes has been assayed on the bacteria Staphylococcus aureus and Escherichia coli, and the yeast Candida parapsilosis.

Structural Isomerism
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CNâÃÂàligand can bind through the carbon atom or through the nitrogen atom....

Stereoisomerism
Isomers are different chemical species that have the same chemical formula.
Transition metal complexes often exist as geometric isomers, in which the same atoms are connected through the same types of bonds but with differences in their orientation in space. Coordination complexes with two different ligands in the cis and trans positions from a ligand of interest form isomers. For example, the octahedral [Co(NH3)4Cl2]+ ion has two isomers (Figure 1) In the cis...
