• Two new networks, namely, {[Cd­(bpba)­(H2bptc)1/2·H2O]} n (1), {[Co­(bpba)­(bdc)1/2]} n (2), where Hbpba = 3,5-bis­(pyridin-4-ylmethoxy)­benzoic acid, H4bptc = 3,3′,5,5′-biphenyltetracarboxylate, H2bdc = 1,4-benzenedicarboxylate, have been synthesized hydrothermally and characterized. Compound 1 is a three-dimensional net with a rare jea topology. The flexible pyridyl arms may afford a dimension extension in the crystal structure. While for compound 2 the flexible pyridyl arms are not involved in coordination, the Co­(II) paddle-wheel secondary building units are bridged by the mixed ligands, bpba– and bdc2–, to furnish a two-dimensional layer. In addition, their heterogeneous catalytic oxidation activities toward methyl orange, methyl blue, neutral red, methylene blue, and safranine T (ST) in the presence of H2O2 are investigated in aqueous solution. The results suggested that the photocatalytic efficiency of ST is found to be 100% for MOF-2.
