A joint experimental and theoretical investigation is performed for Ba-Sn-Ga type-I and type-VIII clathrates. The type-I sample shows a semiconductor characteristic which is accords with the first principle simulation. The type-I clathrate follows Zintl-like behaviour and the semiconducting gap is a
## Abstract In the present work we report on the synthesis of typeโI clathrates Sr~8~Ga~16~Sn~__x__~Ge~30โโโ__x__~ (0โโคโ__x__โโคโ12). To find out how the substitution of Sn for Ge affects structural stability and electronic structure, the structural and electronic properties for Sr~8~Ga~16~Sn~__x__~
