•Polymer 1 is the third homonuclear 3D framework with chelidamic acid.•The chelidamic acid in 1 exhibits two different coordination modes.•Polymer 1 presents a novel binodal (4,6)-connected 3D topology (44.62)(44.610.8)2.•Polymer 1 can act as good candidates for efficient blue emission materials.
The aqueous solution reaction of chelidamic acid (H3CAM), succinic acid, CdCl2·2.5H2O in the air at 50 °C, along with little of ammonia added dropwise, gave rise to colorless crystals {Cd2.5(CAM)(HCAM)(H2O)7·1.5H2O}n (1), which presents an interesting (4,6)-connected 3D structure. Notably, 1 is the third homonuclear 3D framework based on H3CAM ligand, which acts as two different μ4/μ5-bridges in 1 and was abbreviated to HCAM2 − and CAM3 −, respectively, in writing molecular formula of 1. Polymer 1 exhibits strong blue photoluminescence at room temperature.
