A novel pentanary selenide (K₃I)[InB₁₂(InSe₄)₃] was obtained via a high-temperature solid-state method. It crystallizes in the hexagonal space groupP6₃22 and features InSe₄tetrahedron consolidated B₁₂icosahedron and 1-D chain constructed by InSe₆octahedron and B₁₂Se₁₂cluster alternatively connected along thec-axis. Second-order nonlinear optical property measurement shows that it is second harmonic generation-active. Theory calculation indicates that it is indirect semiconductor with the energy gap of 1.15 eV.
