Organic-inorganic hybrid new (C 8 H 18 N) 2 CdCl 4 single crystals were grown using a solution method, with its important physical properties, including in structure, phase purity, thermal analysis, absorption and diffuse reflectance spectra, and photoluminescence characteristic were systematically studied. (C 8 H 18 N) 2 CdCl 4 belongs to orthorhombic P 2 1 2 1 2 1 space group with zero-dimensional non-centrosymmetric structure. A high phase purity was confirmed by PXRD, FT-IR and Raman spectra, and a melting point of 120°C was determined by simultaneous thermal analysis. An absorption cut-off edge of 230 nm and optical band gap of 5.52 eV were determined, with high transmittance range of 300-1900 nm was detected. More importantly, a wide photoluminescence spectra covering visible range were observed, indicating a potential applications of (C 8 H 18 N) 2 CdCl 4 in white light luminescence. This work can supply an important guiding significance for searching new zero-dimensional hybrid d 10 -based metal halides with tetrahedron framework with nontoxic, high stability and some fascinating properties, especially those with white light luminescence performance.
