Two new metal-organic frameworks, namely, Cd(BDC)(Btx) center dot 0.25(H2O) (I) and Co-3(BDC)(3)(Btx)(4)(H2O)(4) (II) (H2BDC = 1,4-terephthalate acid and Btx = 1,4-bis(1,2,4-triazol-1-ylmethyl)benzene), have been synthesized under hydrothermal conditions and characterized by elemental analysis, IR, TGA, and single crystal X-ray diffraction. Complex I exhibits a scarcely reported an eight-connected (4(24).6(4)) net with dinuclear cadmium clusters as secondary building units, whereas complex II displays a three-dimensional co-ordination polymer with a rare (4,6)-connected net described by the (4(4).6(2))(2)(4(8).6(7)) Schlafli symbol. In addition, the luminescence measurements reveal that complex I exhibits strong fluorescent emissions in the solid state at room temperature.
