Noncentrosymmetry (NCS) is a prerequisite for second-order nonlinear optical (NLO) materials. In this work, a new polycation-substitution-induced centrosymmetry (CS)-to-NCS transformation strategy was applied in CS RbGaS₂, affording two novel NCS salt-inclusion chalcogenides: [ABa₂Cl][Ga₄S₈] (A = Rb...
