摘要：
Unexpected nonlinear variation in the composition and optical band gap was observed in an alloyed open-framework metal chalcogenide composed of supertetrahedral clusters. A tentative hypothesis was proposed to explain how the title compound [In28Se54(H2O)(4)].24H(+)-PR.nH(2)O (PR = piperidine) exhibits a limitation in the S-alloying level and a large variation in the optical band gap.
