Crystal structures of iron based superconductors are introduced. Powder neutron diffraction measurements reveal that their crystal structure and superconductivity are strongly correlated. Superconducting transition temperature (Tc) attends maximum value when FeAs4-tetrahedrons form a regular shape. An ideal crystal structure for achieving higher Tc is discussed.
