Owing to the unique crystalline structures and chemical properties of transition metal interstitial compounds,recent advances in their synthetic methods and applications to several reactions were reviewed.

Dipole moments, polarizabilities and first hyperpolarizabilities of a series of transition metal complexes have been studied by employing various exchange-correlated potentials within the density functional theory (DFT).

Competing orders and collective phenomena in transition metal compounds;

By the first principles plane-wave pseudopotential calculations based on the density functional theory,we studied the equations of states and structural properties of transition metal compounds OsB_2 and OsO_2 and the possible high pressure phase transitions of OsO_2.

Transition metal compounds is a main topic in condensed matter physics for their interesting and abnormal properties, such as high-T_c superconductivity, high thermoelectric efficiency, et al, which have attracted much attention of researching.
