Large single crystals of Si30.3(8)P15.7(8)Se7.930(3) and its Te/Ge substituted semiclathrates were successfully synthesized. In semiclathrate Si30.3(8)P15.7(8)Se7.930(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 Si32P14Se7, and photoelectric response and diamagnetism were observed in Si30.3(8)P15.7(8)Se7.930(3). The full story can found in the Communication by H. Zhang and co-workers on page 9505 ff.
