    Introduction: Coordination chemistry is exactly it is, the chemistry of metal atoms "coordinated" by molecules and atoms. Coordination chemistry has always been a challenging task to the inorganic chemist. In the recent days of chemistry this seemed unusual (the name complexes) to define the usual rules of valency. But now-a-days this compramise a large body of current inorganic research. A survey of various articles is recent issues of journal Inorganic chemistry indicates that perhaps 70% could

    Chemistry is the study of everything. Usually, what comes to mind when we hear chemistry is a laboratory filled with equipment and tools that are related to Chemistry. However, this is not how and what Chemistry really is. When we were younger, we were taught about the basics of Chemistry; what it is and how is it important to life. We know that chemicals are tied with Chemistry, just by the name itself we can derive that connection. Chemicals are related to matter, not only that but everything around
