Abstract: A two-dimensional organic-inorganic hybrid perovskite C7H12N2PbBr4 has been grown via a solution-cooling process by employing the organic cation-2-(2-aminomethyl) pyridinium to control the hybrid compound. The structure of C7H12N2PbBr4 was determined by single-crystal X-ray diffractions to be orthorhombic(Pbca, No.61), with the primitive unit cell of dimensions:a=1.7023 nm, b=0.8289 nm, c=2.0224 nm, and Z=8. The inorganic sublattice is built up from corner-sharing PbBr6 octahedra forming infinite two-dimensional layered sheets. The organic cations (2-(2-aminomethyl) pyridinium) adopt obviously distorted configuration to connect the inorganic sheets by special hydrogen bonding. Moreover, optical absorption is used to gain more information of the title compound. The characteristic photoluminescence emission peak is located at 422 nm.
