Abstract	Six novel metal–organic frameworks (MOFs), $\{Mn(bpydb)(bpyHdbH)\}_{n}$ (1) $\{[Co_{2}(bpydb)_{2}](H_{2}O)_{0.5}\}_{n}$ (2), $\{[Ni_{0.5}(bpydbH)(H_{2}O)](DMF)_{2}\}_{n}$ (3), $\{[Cu_{2}(bpydb)_{2}](H_{2}O)_{0.5}\}_{n}$ (4), $\{Zn(bpyHdb)_{2}\}_{n}$ (5) and $\{[Cd_{0.5}(bpydb)_{0.5}(DMF)](H_{2}O)\}_{n}$ (6), were successfully synthesized by assembling transition metal salts with trigonal heterofunctional ligand 4,4′-(4,4′-bipyridine-2,6-diyl) dibenzoic acid $(bpydbH_{2})$ under hydrothermal and/or solvothermal conditions. Compound 1 features a rare 4-fold interpenetrating (3,5)-connected framework with hms-type topology. Isostructural compounds 2 and 4, constructed by $M_{2}(COO)_{4}$ secondary building units, exhibit a robust 3D framework with alb topological type in 2-fold interpenetrating mode. Compound 3 consists of 2D (4,4) networks, which are further assembled into the new topological framework with the symbol $(5^{3}·6^{2}·8)(5^{3}·6^{3})_{2}$ through O–H⋯O interactions. Compound 5 manifests a novel 4-connected interpenetrating framework, constructed by 2D (4,4) layers and interbedded N–H⋯O interactions. Non-interpenetrating honeycomb networks are observed in compound 6, and further packed into a 3D framework featuring 1D channels. The magnetic susceptibility of compound 2 indicates antiferromagnetic interactions between cobalt ions. The photoluminescent properties of 5 and 6 were investigated in the solid state at room temperature.
