Organic compounds are molecular compounds that contain mainly carbon and
hydrogen atoms. Since inorganic chemistry deals with all compounds other than organic
ones, the scope of inorganic chemistry is vast. Consequently, we have to study the
syntheses, structures, bondings, reactions, and physical properties of elements, molecular
compounds, and solid-state compounds of 103 elements. In recent years, the structures of
crystalline compounds have been determined comparatively easily by use of single
crystal X-ray structural analysis, and by through the use of automatic diffractometers.
This progress has resulted in rapid development of new areas of inorganic chemistry that
were previously inaccessible. Research on higher dimensional compounds, such as
multinuclear complexes, cluster compounds, and solid-st
