Abstract

Lewis basic Pt₂(μ-Se)₂(PPh₃)₄reacts with In(ClO₄)₃ to give a rare platinum–indium selenido aggregate, {[Pt₂(μ₃-Se₂)₂(PPh₃)₄]₂In₂(μ-Se)₂}{ClO₄}₂. Single-crystal X-ray diffraction analysis revealed a hexametallic framework supported by a planar {In₂Se₂} square sandwiched by two {Pt₂Se₂} hinged butterfly moieties. This structure resembles that of the semiconducting anion [(Ga₆Se₁₄)10⁻] by having a common double-tetrahedra {M₂Se₆} core. The planar {M₂Se₂} ring also exists in other semiconductors like In4Se3 and TlSe.
