Syntheses, Crystal Structures, Antimicrobial Activity and Thermal Behavior of Copper(II) Complexes Derived from
Abstract:
Two copper(II) complexes, [CuL2(EA)] (1) and [Cu2L4(PA)2]·2H2O (2·2H2O), where L is 1-naphthylacetate, EA is N,N-diethylethane-1,2-diamine, PA is propane-1,3-diamine, have been prepared and characterized. Structures of the complexes have been characterized by single-cyrstal X-ray diffraction. Complex 1 is a mononuclear copper(II) compound, with the Cu atoms coordinated in square planar geometry. Complex 2·2H2O is a centrosymmetric dinuclear copper(II) compound, with the Cu atoms coordinated in square pyramidal geometry. Single crystals of the complexes are stabilized by hydrogen bonds. The effects of the compounds on the antimicrobial activity against Staphylococcus aureus, Escherichia coli, and Candida albicans, as well as thermal behavior of the complexes were studied.

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 CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can...
