Description/Focus and Content: One of the ultimate goals of chemistry is to control the absolute and relative configurations of all elements and freely design the bonds between the elements. Therefore, controlling the absolute configuration and asymmetry of the metallic center is an important key to open up science for new materials of metallic elements that account for approximately 80% of the periodic table. A new scientific principle “Coordination Asymmetry” was created by the development of methodologies to build asymmetry and chirality of structural and electronic states with metal complexes and coordination space obtained from assembled complexes and its nano to micro level assembly based on the molecular level control of the coordination sphere of metal complexes. Therefore, this symposium on“Coordination Asymmetry” will focus on the design and synthesis of asymmetric coordination sphere and development of anisotropic assembly method with theory, experiments, and measurements of metal complexes by understanding metallic elements as well as three-dimensional control of the coordination sphere, reaction, and physical properties expression field.
