Abstract

Two metal coordination polymers, {[Zn(bpdc)(bip)]·2H2O}n (1) and [Zn(tdc)(bip)] (2) [H2bpdc = biphenyl-4,4’-dicarboxylate, H2tdc = thiophene-2,5-dicarboxylate, bip = 3,5-bis(imidazole-1-yl)pyridine], have been synthesized and characterized by IR, elemental analysis, XRD, and X-ray single-crystal diffraction. In 1, bpdc and bip link Zn(II) ions into a corrugated 2D layer. The corrugated 2D layers polycatenate each other, yielding a 2D→3D polycatenation net. In 2, dinuclear Zn(II) units are formed by bip and further connected by tdc to construct a 2D 3-connected framework. The luminescent properties of 1 and 2 are investigated in the solid state at room temperature.
