This work has been devoted towards the exploitation of the synthesis of transition metal hydrazine cinnamates using transition metals salts, hydrazine hydrate and cinnamic acid. The study includes a detailed presentation of coordination complexes, chemistry of hydrazine, cinnamic acid and transition metals, their applications, and various metal hydrazine carboxylates. The scope and objectives of the study are also discussed. The specifications of all the materials used in the study and the details of the different experimental techniques employed in this study are elaborated. The main part of the book illustrates the synthesis and characterization of the different metal hydrazine cinnamates and the methods used for this.
