In this study we extended the family of DJ halide perovskite containing diammonium cations, by preparing, solving the structure, and characterizing novel lead bromide materials containing 1,3-phenylenediammonium (1,3-PDA), 1,3-xylylenediamimonium (1,3-XDA), 1,4phenylenediammonium (1,4-PDA), and 1,4-xylylenediamimonium (1,4-XDA) cations. We showed that the choice of the organic cation has great influence on the topology of the structure, determining whether the layered perovskite structure can occur or not. Consistently, the degree of freedom of the organic cation deeply affects the interactions with the inorganic framework, influencing octahedral distortions and thus the optical properties of the compounds. Thanks to detailed structural and optical characterizations, we could link the differences in the optical properties, such as the nature of luminescence, to the structural parameters. In fact, samples with high degree of distortion (containing the 1,3-PDA and 1,4-PDA cations), i.e. with larger values of   and  oct show a dominant role of the broadband emission, while the presence of relatively undistorted octahedra when 1,4-XDA cation is the spacer, leads to a mixture of narrow and broadband emission. However, the difference in optical properties, and in particular in the intensity of the emission, cannot be completely explained based on common and traditionally used parameters of the distortion in the octahedral layers. This suggests that further investigation into the relationship between structural properties and broadband luminescence in low-dimensional perovskites containing diammonium cations are called for to identify precise design rules allowing to develop efficient perovskite-based broadband and white light emitters.
