Abstract:
Two novel dinuclear complexes [Co(2)(L)(2)(phen)(2)·2H(2)O](n) (1), [Co(2)(L)(2)(bipy)(2)](n) (2) (where phen=1,10-phenanthroline, bipy=2,2'-bipyridine, and L=biphenyl-2,4'-dicarboxylic acid) have been synthesized and characterized using IR, (1)H NMR, element analysis and single-crystal X-ray diffractometry. The binding of the complexes with HC-DNA (HeLa cells DNA, which was extracted by ourselves) was investigated by fluorescence spectrum. The experimental results show that the two complexes have the ability to bind with extracted HC-DNA. Gel electrophoresis assay demonstrates the ability of the complexes to cleave the extracted HC-DNA. The complexes exhibit a higher cytotoxicity against tumor cells as against normal cells in vitro. Further more, the apoptotic tests indicate that the complexes have an apoptotic effect on HeLa cells.

Colors and Magnetism
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human eye.
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 be...
Crystal Field Theory - Octahedral Complexes
To explain the observed behavior of transition metal complexes (such as colors), a model involving electrostatic interactions between the electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals.
CFT focuses on...

Metal-Ligand Bonds
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...
