Two new three-dimensional (3D) multinodal Cd(II)–organic frameworks, [Cd₃(dccpa)(bipy)_0.5(H₂O)₄]·5H₂O (1) and [(CH₃)₂NH₂]₂[Cd₁₁(dccpa)₄(DMF)₄(H₂O)₈]·4H₂O (2) (H₆dccpa = 3,4-di(3,5-dicarboxyl phenyl) phthalic acid, bipy = 4,4′-bipyridine), have been prepared and fully characterized. Compound 1 possesses a 3D neutral framework with a new (6,6,7)-connected topology based on a single trinuclear cluster, while 2 features a 3D anionic framework with a new (5,6,6,10)-connected topology containing mixed trinuclear and pentanuclear clusters. Remarkably, 1 and 2 show promising photocatalytic activities toward the degradation of rhodamine B and methyl blue, which suggests that different kinds of cluster units may exert different impacts on the decomposition of organic dyes.
