      This work is a continuous of our previous work in M.Sc study. Our previous work was concerned with the use of locally produced V₂O₅ (technical grade) in the preparation of catalyst successfully employed in the oxidation of n-butane to Malice Anhydride. The catalyst was evaluated using geomechanic system (France) specially built for catalytic test and modified to our proposes. The results had indicated to a functional catalyst.

Taking in account the basic ideas in coordination chemistry governing the structure and reactivity of these compounds especially those of Palladium and Platinum complexes, a new set of Pd(II) and Pt(II) square planar complexes with varying structural isomerism have been prepared and studied. Their structure and spectral behavior have been discussed based on hard and soft acid base principles, back π-bonding, and redox behavior.

This study included extraction of total flavonoids compounds from Matricaria chamomile flowers that grown in Iraq. The extract was brown color crystals composition.
