Large single crystals of Si 30.3(8) P 15.7(8) Se 7.930(3) and its Te/Ge substituted semiclathrates were successfully synthesized. In semiclathrate Si 30.3(8) P 15.7(8) Se 7.930(3) because of the Si3−Si3 bond rotation tetrakaidecahedron was broken at the same time as the Se1−Si3 bond was formed. Similar structures were observed in Te and Ge partial substituted compounds. Theoretical calculations showed a semiconducting feature based on an ordered model of Si 32 P 14 Se 7 , and photoelectric response and diamagnetism were observed in Si 30.3(8) P 15.7(8) Se 7.930(3) .
