Salt-inclusion chalcogenide is a promising infrared (IR) nonlinear optical (NLO) system for its potential in mitigating the incompatibility between second harmonic generation (SHG) efficiency and laser-induced damage threshold (LIDT). Herein, a new noncentrosymmetric salt-inclusion chalcogenide, [Rb4Cl][Cd11In9S26] (1), was prepared by high-temperature solid-state method. It features a distinctive [Cd11In9S26]3- host framework composing of pseudo-T2-Cd3InS10 and T2-CdIn3S10 supertetrahedra, which are rare in known salt-inclusion chalcogenides. Remarkably, compound 1 exhibits a phase-matchable SHG signal (0.23 times that of benchmark AgGaS2), which mainly originates from the distorted CdS4 and InS4 tetrahedra in the host moiety. Moreover, it possesses moderate band gap (2.32 eV) and high LIDT (4.9 ×AgGaS2). Such high LIDT may due to its small thermal expansion anisotropy.
