Abstract

Theoretical studies for calculating the molecular structure and electronic properties of Cyclohexane
-1,2-diamine-oxalate- platinum metal complex by using density functional theory (DFT) for get electronic
properties and time dependent density functional theory (TD-DFT) for get excited state with B3LYP-SDD
basis sets at the Gaussian 09 of programs. The electronic states of the system have been calculated depend
on Koopmans’ theorem.
The results showed that the excitation energies of oxaliplatinum lie in the UV region of electromagnetic
radiation with very high biological reactivity, where The absorption spectra of complex recorded with
wavelength (344.69nm), oscillator strength (0.0002). From calculations of the HOMO - LUMO energies,
energy gap, hardness and softness, all this results showed oxaliplatinum are more soft and can easily interact
with enzymes because the enzymes are big soft molecules. Thus, the optimized geometry shows a good
agreement with the experimental results.
