Low-dimensional organic–inorganic hybrids have been explored as photoluminescent (PL) materials with high photoluminescence quantum efficiencies and tunable band structures [1]. Herein, we present two hybrid compounds, namely, [3AMP][CdX4], (3AMP = 3-(Ammoniomethyl)pyridinium, X = Cl− (1), and Br− (2)) based on one-dimensional (1D) chain-like [CdCl4]2− and zero-dimensional (0D) discrete [CdBr4]2− tetrahedron, respectively (Figure 1). Both compounds show distinct excitation wavelength-dependent photoluminescence originating from different packing of organic molecules and inorganic units. Our work demonstrates dimensionality modulation by the exchange of the halogen atom that might provide effective tunability of PL properties in low-dimensional hybrids.
